Cannot view PDF forms (with Signature) in Workspace Error : "SigDict/Contents illegal data"

Avatar

Level 7
Hello,



With Jasmin's help, I am able to import a PDF form which is digitally signed >> view it in Workspace >> click Approve/Decline for archiving. Thanks Jasmin !



When I view the form in workspace, I get a "Atleast one signature is invalid" prompt on the top left corner of the window. Upon clicking the "Signature Panel", it says "The Signature is invalid" with a description of "SigDict/Contents illegal data"



Once the process is complete, I am unable to open the same form. I get an error message in Adobe Reader (within workspace).



"Adobe Reader could not open '_7358722841708390983-102[1]' because it is either not a supported file type or because the file has been damaged ( for example, it was sent as an email attachments and wasn't correctly decoded)"



Any help will be highly appreciated.

For everyone's reference.



I figured out the "Signature is Invalid" message.



This was my fault as I used a Form Augmenter (insert form bridge) to a signed form which broke the PDF.



After removing that module, I no longer got that message. However, once I approve the form I could no loner view it and I would still get an error.



"Adobe Reader could not open '_7358722841708390983-102[1]' because it is either not a supported file type or because the file has been damaged ( for example, it was sent as an email attachments and wasn't correctly decoded)"



Anyone know why ?
