I have setup the deployment extension to automatically deploy from our source control on Azure Dev Ops.
Initially it worked but, when we migrated to a branch per tenant pattern, it stopped working.
The web hook fires and deployment starts, but it fails with the error:

Value cannot be null.

Parameter name: versionDescriptor

It's also worth noting that, on the table showing deployment history, the branch field is empty. I have tried removing and reinstalling the extension, but the result is the same.
