I have configured the plug-in but every time I try to submit changes I get the following error: Incorrect configuration: Please set up the ‘submitChangesValue’ and ‘submitChangesSaveInto’ parameters.

I implemented the Google Maps Component Plugin in the Dev and Test environments, and everything worked as expected. However, after deploying to Production, Google Maps is not functioning. Upon inspecting the browser console, I see the following error: Failed to load resource: the server responded with a status of 404 (Not Found) - Googlemap.svg. I&rsquo;ve checked the server configuration, and it appears to be identical to the other environments. Any idea what could be causing this issue?&quot;

Hello Community, I have developed a custom plugin for Appian and have completed initial testing within the Appian testing environment. Now, I would like to test this plugin outside of the Appian platform to ensure its robustness and compatibility in different scenarios. Could anyone suggest tools, frameworks, or best practices for testing Appian plugins externally? Are there any recommended approaches for simulating the Appian environment or mocking necessary services for comprehensive plugin testing? Any advice or shared experiences would be greatly appreciated! Thank you,

I have a&nbsp;Process model where the flow of nodes is like this:&nbsp;I am sending a file to SFTP temporary folder, and adding a delay time node for 10 seconds and next i am using a Rename and Move file over SFTP smart node where i am renaming the file and then moving it from temporary SFTP folder to another permanent folder. At this point, the system is throwing the below error: &#39;Error renaming file in the remote server. See application server log for more details. Error Message: Specified file path is invalid.&#39; My guess here is that the file is not having enough time to move from one folder to another, because if I just restart the node its working fine. How do i add a delay in the &#39;Rename and Move File Over SFTP&#39; so that the file will have enough time to move from one folder to another.&nbsp;
