Hi, I am having issues with the sync between Appian data types and corresponding Java plugin objects. In Appian, I have two CDTs called ‘AttachmentList’ and ‘AttachmentDescriptor’. They were generated from ‘AttachmentList.xsd’ and ‘AttachmentDescriptor.xsd’, respectively.  As seen in the screenshots above, ‘AttachmentList’ contains one field called ‘Attachments’, where ‘Attachments’ is an array of ‘AttachmentDescriptor’ data types. These two CDTs share the same namespace. I have a custom Java plugin node that takes an AttachmentList data type as input. In the process model that uses this Java plugin node, I set up AttachmentList as shown below. /resized-image/__size/640x480/__key/communityserver-discussions-components-files/19/Screenshot-2025_2D00_11_2D00_28-at-1.54.52_2F20_PM.png Here is the code in the Java plugin source file for setting up AttachmentList as input: @Input(required =

Hello, We are currently integrating Appian with our SharePoint Online tenant. We created a SPN with delegated permissions in Azure as stated in your documentation (https://docs.appian.com/suite/help/25.1/Integrating_Sharepoint_with_Appian_CS.html).  That integration works fine with Authorization Code authentication (Client ID + Secret) https://docs.appian.com/suite/help/25.1/sharepoint-connected-system.html#sharepoint-authorization-code-authentication but this is not the authentication mechanism we would like to use. Our goal is to use Client Credentials with a certificate: (https://docs.appian.com/suite/help/25.1/sharepoint-connected-system.html#sharepoint-client-credentials-entra-id-authentication) We generated a certificate and got all the requested information: private key in pem format, thumbprint, etc.  The authentication is failing with 401 error: If we change the delegated permissions to application permissions, then it works fine: Our preference is to use delegated

Hi Team, For one of our clients, we have a requirement to move Appian documents to GCP. To meet this requirement, I have created an Appian Web API that exposes the document when the document ID is passed as a parameter. However, I am unable to test the API within Appian as it is giving 404 error while I'm testing it. Here is the Web API code, which was generated using the available Appian API templates, along with the response I receive when testing it by passing the document ID of an Appian document. Could you please assist?

We are trying to integrate with docusign embedded component in appian.  I used a code grant authorization with a connected system, with a single user.  When the token is not valid i go to the connected system and click on authorize. And like that i can even sign embedded in appian or with the url generated. The problem is that we have a requirements to provide signing with docusign for two distincted users, That user are not administrator or designer(like me) so cant click the authorize button everytime. And i see that in the connected system are not a user reference to pass.  So how can i authorize two different user with codegrant? I have to use two different connected system with a different secret keys? Use an a!authorizationLink?

I am attempting to develop a feature for my application where a user can add a pin on a map using the esriMapMarkerField component. I've used it before with readOnly enabled, but not to gather user input. It seems like I'm supposed to add the relevant saves in the "onNewPointAdded" parameter, but the documentation is sparse on specific guidance with it. I would have assumed there would be some function variable to pass into the save, but I've come up with nothing. My code so far is below... does anyone have suggestions or an example they could provide?a!localVariables( local!pointData: {}, esriMapMarkerField( esriConnectedSystem: cons!MR_CS_ARC_GIS_MAP, baseMap: "oceans", secondaryMap: "satellite", zoomLevel: 3, mapCenter: { latitude: cons!MR_ESRI_MAP_CENTER_LATITUDE, longitude: cons!MR_ESRI_MAP_CENTER_LONGITUDE }, isReadOnly: false, maxSelection: {point: 1, polyline: 0, polygon: 0}, pointData: local!pointData, onNewPointAdd

For Appian version 24.2.1295.0 and Excel Tools version 2.6.3, I am getting following error.  ERROR ImportExcelFileToDatabase ORA-17041: Missing IN or OUT parameter at index: 2 Is this due to a version miss match ? Which version will be suitable with my current version of Appian and will upgrading the plugin cause any issues with the older code?

I am using iCal Plugin 6.0.0 in OnPremise Appian environment, to send an invite to Outlook. The node gets completed successfully in the PM and even a meeting uId is generated. However, meeting invite is not received in recipients' inbox(this recipient is able to receive normal emails from the same environment). On further investigating the tomcat logs, it looks like an issue with smtp/server errors, which is not able to send the invite. Please share thoughts/suggestions. Thanks in advance. Nitika

Hello- Need some advice on the best possible approach to make a servlet POST call from a servlet browser. Our Objective : From Appian user servlet browser, upload large files using graph API to sharepoint using chunking. This solution works perfectly fine on standalone eclipse but getting hiccups on Appian cloud. We cannot do this using traditional route as sharepoint API has a limitation of 250MB, our files are 1gb & beyond. couple of approaches i tried : Moved all the logic directly into the browser, including the session creation...but Azure rejected this approach not allowing to create session from the browser... 2nd approach Appian UI to HTML interface making a Servlet POST call to initiate a upload graph api session & return the token back to HTML & from here making all the grinding to sharepoint, here we are getting CSRF token rejection  Just want to know if there is a best working approach we could use. Any help here is really appreciated.

We are encountering an issue during the integration of our application with an external Angular application via an IFrame. When a record action is invoked as a dialog box from the third-party Angular application through the IFrame, the dialog box renders as a blank page. Conversely, the same record action functions correctly and displays expected content when accessed directly from within Appian. Upon inspection, we observed that the <appian-dialog-body> HTML tag is empty when the action is initiated through the IFrame, which is not the case when accessed natively within Appian. Attached below are images to understand this better Appian IFrame For context we have already updated the following details in server config files to no avail:- on server set Clear-Site-Data: "cache", "cookies", "storage", "executionContexts"  Clear-Site-Data Header Issue The Clear-Site-Data header is being sent with an unrecognized type

Hi, I'm not very knowledgeable about encryption algorithms, but I'm trying to figure out if I can send a text encrypted in AES (with the Encryption Functions plugin) so that it can be decrypted by a service external to Appian, using RSA.My guess is to use the RSA public key and store it in the Secure Credential Store of the plugin. This way, I encrypt in AES but with the RSA public key. Now, can the external service decrypt with its private key? thks

Hi when I generate a word document with an image example: {logo: CONS!APP_IMAGE} works perfectly, but when I have more than one image in the template. For example logo2 and I call the smart service as follows {logo: CONS!APP_IMAGE, logo2: CON!APP_IMAGE2} I get the following error: freemarker.core.NonSequenceOrCollectionException: The value you try to list is an extended_hash+string (fr.opensagres.xdocreport.document.images.ByteArrayImageProvider wrapped into f.e.b.StringModel), thus you must specify two loop variables after the "as"; one for the key, and another for the value, like <#... as k, v>). ---- FTL stack trace ("~" means nesting-related): - Failed at: #list logo as logo [in template "fr.opensagres.xdocreport.document.docx.DocxReport@7f2dbfc!word/document.xml" at line 4, column 6773] ---- Plugin: Advanced Document Templating      Version: 1.1.0      Smart Service: DOCX From Dynamic Template

Hello, I am trying to set up a Google Drive integration with a service account and I have created some shared drives. You can see based off the screenshots the folderID is correct and therefore should be creating a folder in that root folder but it is failing to create in the shared drive (I have done a POC with a personal drive and it worked flawlessly) Is there an option I am missing here? The only operation I found that works is the "Find File" operation where it has the "SupportsAllDrives" parameter set to true. 

I have an integration with S3 bucket, which is a type of modify data. This integration pull the documents and store in folder. Now I need to provide a link to user, so that user can click the link and get the documents download. How can I do it in a single click.

Hello. In one of our projects, we need to download the files sent by clients through WhatsApp in order to perform a series of internal checks. We have reviewed some applications available in the marketplace and found the following: WhatsApp Business Connected System: Doesn't allow downloading files from WhatsApp. Symphony Connected System: In theory, it does support this functionality. However, we haven’t been able to test it yet, as it also requires a Symphony license. Has anyone here had experience using Symphony Connected System? Do you know of any other application that allows downloading files from WhatsApp, or any alternative approach you would recommend for this type of integration? Thank you very much in advance for your help. Best regards
