Issues when executing correspondence fragment from correspondence rule when resuming a case from Listener

Hi Everyone,

We have a requirement to send an email with assignment link to internal user(group mailbox).

We have a new correspondence rule created and it has correspondence fragment(this is to build assignment link) rule.

When the actual user submits a case an email(this is configured through send email shape in flow) is getting sent successfully with the assignment link and no issues, where as when the case is resumed by listener(in this scenario case is sitting in a work queue) the email is being sent but there is no assignment link and it's throwing an exception.

It seems when executing from listener it's not finding the corr fragment as per stack trace.

Note: In both working and exception scanario's page context is pyWorkPage and no issues with page context.

Below is the full stack trace of the issue from tracer/logs.

@Giri Paruchuri I think there seems to be some issue with the logic written as part of the correspondence fragment. Could you try these points:

  • Delete everything as part of the fragment and test the scenario again
    • If error occurs
      •  Check if the fragment is available as per runtime ruleset stack of listener
      •  Check if you made of "Using Page" parameter while inserting the fragment in the corr rule. If yes, make sure that this page exists during run time
    • If there is no error then you need to check the property or page references as part of the fragment

@BhanuPrakash_G _ Thanks for your reply.

Verified all the above steps, 

1. Deleted and created fragment with different name, still getting same issue.

2. Traced and able to see the rule getting picked at runtime

3. Passed pyWorkPage as parameter for Using Page param and can see the page available and able to see the same in tracer

4. It's not error and it is an exception which was shared as part of the initial request.

Thanks,

Giri
