When using OnBase Unity Client (ECM) to index documents, the application will display PDFs within its internal viewer. This was working properly until release 22.003.2028x in November. After this, the viewer would give the attached error when attempting to display documents. It was not consistent, but was happening at least half the time - especially with PDFs that had fillable fields. The user would have to completely close out of the Unity Client application and start the process over. Sometimes it works for them the 2nd time around and sometimes it doesn't. They would have to repeat this process until the document was successfully indexed.

Then when the workstations were updated with 22.003.20310 in January the issue let up and almost disappeared, but then reappeared with the February 22.003.20322 release.

We have removed the enhanced security settings for these users (enable protected mode at startup and enable enhanced security) have been disabled.

The users are running Adobe Pro on Windows 10, but we've also tried uninstalling Pro and installing Adobe Reader - with no change in the errors being received.

We tried switching to Edge as the default program for PDFs as well, with no change in the errors.

If this can't be fixed, we may need to consider using a different PDF program.

Please advise.
