Hi Ladislav Jaroscak ,

Thanks for reaching out!

Could you please let us know the appian version that you are using?

Hello,

when using encryption smart service we keep getting error message

"In order to access this method, this Document needs to be retrieved via ContentService.download()"

The output document shows in appian designer, has corresponding extension, but is of size <1KB (0 probably) and its not downloadable. In PM, when using PV to store this as an output of the smart service into, the PV ends up with no value.

Any sugggestion what could be going wrong?

Hi vigneshe 

We are also having difficulties to reproduce it now, and the concerned process instance has been archived.

I will update you if I have anything new

thanks again

Hi mokc0038 ,

We can't reproduce the issue that you mentioned. Kindly provide details on the configured parameters for further investigation.

Hi everyone 

After doing some tests (after your last delivery), we have a new error happening everytime when trying to decrypt a file without creating a new file.

The error message is always : Changed to Invalid UTF-8 input

Here are detailed logs : 

decryptedFile = KeyBasedLargeFileProcessor.decryptFileWithExtension(cs.getDocumentInputStream(fileToDecrypt), cs.getDocumentInputStream(privateKey), pwd.toCharArray(), decryptedFileName, existingDocument, createNewDocument, saveToFolder, cs);

1. Updated libraries.
2. Updated the PGP Decrypt File Smart Service to save the decrypted document in the original source file’s format.
3. Updated the file extension, create new document parameters to be optional for all the smart services.
4. Added validations for the create new document and existing document parameters.
