Error Message when Saving ticket

Is that on the latest version?

the version is 2.7.6 - Build #12.7.6.8342-HF1

Sounds like a Checklist has been deleted but still exists as linked to the Request type.

WHD12.7.6 was a little flaky with this new functionality and it has got a little better with the later releases but I suspect some interaction with the database might be required, best log with Support for guidance.

Thanks .. let me log a case.

You might try to reboot WebHD, stop/restart the service.  I have had that resolve some issues like this where I removed some Request Types but somehow it kept triggering my Action rules and giving errors.

There is a know issue where if you delete a Request Type that action rules using the 'any of' logic still try to process deleted Request Types. Therefore clear the entries for 'any of' save and then re-select you choices and then save again.

Best to upgrade to the latest version too.
