Principal user is missing prvReadCanvasAppExtendedMetadata privilege for entity 'canvasappextendedmetadata'



We have been deploying our solutions via azure release pipelines and power platform build tools into various environments. During a release today we started getting the error Principal user (Id=GUID, type=8, roleCount=1, privilegeCount=1209, accessMode=4) is missing prvReadCanvasAppExtendedMetadata privilege for entity 'canvasappextendedmetadata'. 

We were able to release to this environment many times via release pipes without this issue before.

Also, we were not able to find any user / app registration or service principal with that guid in the environment and in our Azure AD.

We fixed the issue ourselves. 


As part of creating the release pipelines for various environments, we had created a Service application connection to each of the power platform environments. Created a new security role called DEVOPSIntegration as a copy of system administrator role and assigned the user to this role. Not sure how the permissions got changed ( the page to update custom entities probably needs a revisit from the MS Team) but they were misaligned to what the System admin role had in TEST and UAT environments (DEV and Prod were ok). Once we deleted the security role and re copied the permissions from system admin role, the deployments are all fine now.
