Executing pipeline in AML from Logic Apps stopped working

Question

Hello! I have a few logic apps for my company that trigger ML pipelines at specific time intervals. I followed the documentation on how to set up a logic app and trigger pipeline to the letter and for the past 2 months everything was working fine and my logic apps were able to trigger the ML pipelines with no issues. However, on 12/08/2021 at exactly in between 1:30PM - 2:30PM CST, every single pipeline starting failing and they continue to do so up until now. I noticed that we are now receiving this error on every execution:

"UserError: Response status code does not indicate success: 400 (User starting the run is not an owner or assigned user to the Compute Instance). User starting the run is not an owner or assigned user to the Compute Instance"

My Logic apps are setup with "Managed Identities" of Owners (like the documentation explains). My last successful run for all the logic apps was on 12/08 before 1:30PM CST. Did something change on both Azure Logic Apps and Azure ML that is now causing this issue? Any help is greatly appreciated as this is impacting my company's business.

I ran into this same issue in a slightly different context. I didn't manage to figure out the root cause but managed to resolve it in practice by standing up a Compute Cluster instead of a Compute Instance (see https://learn.microsoft.com/en-us/azure/machine-learning/how-to-create-attach-compute-cluster?tabs=python)
