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

[![Validation failed](https://i.stack.imgur.com/bdljp.png)](https://i.stack.imgur.com/bdljp.png)

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.
