Hi,
The issue seemed to be some sort of race condition where processing a single image worked fine but trying to process multiple images at the same time caused the issue.
Reverting to the previous version was not possible, so with the aid of Appian support the plugin was removed, restart the application server and then reinstalled the plugin.
The same process had to be performed to upgrade each of our environments.
This cured the issue.
Please note that the same sort of issue was logged here (by me) about two years ago.
Hope this helps
Hi pauls0008 we are having the same issue. Have you found any other detail or workaround? Was there any update on this?
When I try to merge PDF I get the following error: "java.security.NoSuchAlgorithmException: SHA-2 MessageDigest not available". Could someone tell me why this error may occur?
Adding function to find page where text is present
aaah sorry to read but nice input. instantly checked for the auther and its even appian themselves. Hoping they fixing it.
As of version 2.5.2 (and found on the older editions we try, such as 2.2.5 and 2.2.9), the PDF to Image smart service results in Filled Checkboxes (from a user-fillable form) rendering not as checked boxes, but as boxes with a smaller box inside them (as if, instead of a "check mark", each checkbox is being given a "broken image placeholder"). This is a big problem for us as this functionality was the one way we'd come up with to overcome a major blocker otherwise, but will be useless to us with this bug in-place as it's incomprehensible to end users.
Any update please as this is causing production issues requiring manual intervention on many image conversions each day.
Thanks
Just updated to 2.5.2 on Appian 24.2 using smart service convert Image to pdf.
Following update errors are recurring. The errors from the system log are shown below. Any advice to resolve pls?Thanks
