Defender Autotask Internal Server error 500


We are currently running into some issues with our autotasks, we have a lot of pending transactions that are not going through for our autotasks, each autotask also do not show any logs, which makes it very hard to understand why there is an error.

The errors did not appear yesterday and seemed to work correctly, and we have not done any changes which should affect this, which is why we are curious if its related to Defender backend.

We are trying to call an AutoTask, from another AutoTask, using AutotaskClient

Our error:

I have removed sensitive IDs as it's in prod, and prefer to share them in DM´s rather than publicly.

Autotask, Relays, Sentinels

Hey @Felix_Theodoor -

Sorry for the issues, please send us an email at with the autotask ID so we can debug this issue.
