Hi,
I'm seeing this screen in one of my interface when I open it from process model while debugging / from Tempo. Can someone suggest on what needs to be done to identify the issue? There is no change in this interface from couple of years. When I try to populate the information in the designer mode. I'm able to view it without any issue.
Discussion posts and replies are publicly visible
Any info in the tomcat log file?
What should I be looking for?

I'm not sure that snippet contains your error. Were those at the same time as the error? (and remember all logging is GMT)
Are you able to reproduce in a lower environment through the process? As you note when you utilize the same data in /design, all is well.
Is this just one process instance, others are fine?
Sometimes I'll start by commenting out almost all of the interface, re-load the task, and un-comment piece by piece until the error re-appears, to narrow down the search. Trickier in production if this is more than a seldom used process, if you can't reproduce in lower envs.
Hello Chris, I tried to open the interface from tempo at 2:36 PM EST and then copy and pasted the log after that. This issue is currently reproducible in Dev and TEST and We did not see it in PROD.
The second error was generated at the 2:36 ET mark:
2022-02-15 19:36:45,867 [ajp-nio-0.0.0.0-8009-exec-13977] ERROR com.appiancorp.rest.shared.FallbackExceptionMapper - Internal Server Error on REST API invocation. java.lang.NullPointerException
I'm pretty sure I've seen that in my logs without a noticeable front-end issue occurring, however I'm not positive on that.
Are there external calls, web services, etc within the form?
What happens if you comment out your entire interface, other than:
{}
Save, and reload the task? I will note that I haven't seen that type of error generated with an interface issue prior, but it could be and this would rule it out.
Otherwise, if the error is gone, start uncommenting section by section, save, reload.
No, there are no external calls on the interface. I'll try commenting and uncommenting the code and see if we are able to find anything.
