I've created a playbook to create incident in our ticketing system which then returns back ticketing system incident ID which I want to add as comment to Sentinel Incident. However it fails with error 500 and no explanation.
Here's an example workflow, where I have removed incident creation in ticketing system, however adding comment still fails. On another hand, using same connections adding tag/label to incident works fine.
@GunarsL I think that error can be resolved by re-authenticating your Sentinel connector however it will then throw another error about not returning proper JSON which Microsoft is working on resolving.
