Over the weekend, our ADF solution cannot validate any more.

Error message at validation:

DF_Postcode Could not load resource 'DF_Postcode'. Please ensure no mistakes in the JSON and that referenced resources exist. Status: UnknownError, Possible reason: undefined

This includes triggers, pipelines, and dataflows.

We did not do any deployments between Friday and this morning. Any thoughts?

-- Update --

Possibly related, starting a data flow debug is not succesful.

-- Update 2 -- Multiple pop-ups appear when doing a shift F5 refresh of the page. The error message itself is not very helpful.

CodePudding user response：

It does appear there were few changes pushed to ADF over the weekend. However, as the error says, could you check the resources if they are intact or if any properties or values got reset! just in case to be sure to remove user configuration issue.

Check in the ADF studio for all the resources referenced in the error.

If you are using Powershell modules at any point in there, make sure you use the latest one.

Also, for quick check you can raise an issue

Summary of impact: Between approximately 06:30 UTC and 12:30 UTC on 13 Dec 2021, you were identified as a customer using Data Factory V2 in West Europe who may have experienced intermittent errors when accessing resources in this region.

Preliminary Root Cause: We determined a backend service, responsible for processing API requests became unhealthy. This led to intermittent API failing calls for Azure Data Factory resources.

Mitigation: We restarted the backend service which mitigated the issue.
