Fabric Issues (Notebooks and Data Pipelines not loading)

I am having trouble accessing any resources in Fabric (Notebooks, Pipelines etc). Note books are stuck in an endless loading cycle and looking in developer tools I can see an error as below.

Uncaught TypeError: Cannot read properties of undefined (reading 'endsWith')
at join (?__iframeId=e41a3499-9cfb-4807-805e-aee28c84fda2&__iframeType=worker&__environmentName=C1&__extensionName=de-ds&
at loadJs (?__iframeId=e41a3499-9cfb-4807-805e-aee28c84fda2&__iframeType=worker&__environmentName=C1&__extensionName=de-ds&
at Array.forEach (<anonymous>)

at ?__iframeId=e41a3499-9cfb-4807-805e-aee28c84fda2&__iframeType=worker&__environmentName=C1&__extensionName=de-ds&

Also when opening a DataPipeline I just get a blank screen as below.


Is anyone else facing these issues, I have logged a support call with Microsoft.



All working again now.

Same issues here. Tried clearing cookies/enabling them for Fabric but no difference made.

Currently having the same issue.

Pipelines open in blank and notebooks don't load.


Javacript error as follows:

Uncaught TypeError: Cannot read properties of undefined (reading 'endsWith')

I'm having the same problem, seems to be a widespread issue

Yes, I cannot load any of my Notebooks.

Looks as though someone @ Microsoft has made a mess, hoping it gets resolved soon.

Just to add, I cannot access pipelines either. Dataflow gen2 yes, pipelines no.

Yeah me neither, its something to do with the baseUrl being undefined. Just did some debugging of the Javascript on the page.
