Fabric unable to read Synapse Pyspark notebooks edited in VS Code

[JIlicGrECo]

Hello everyone,

Since yesterday I am unable to open any notebook in Fabric web app, that has been previously edited in VS Code using the Synapse extension. The notebooks are written in Pyspark. After the content was published in VS Code using "Publish notebook", I tried to load it in Fabric UI. I got the following screen

One sample diagnostic message from the link is this:

}

Additional info: Artifact ID = d8a973c6-4702-4ed4-89cd-93615867f731

Regardless of whether the notebook is simple or more complex (using the imported packages as well), or whether the notebook was created in Fabric or VS Code, I get the message.

Is this a known bug and is there a workaround? Thanks in advance

Hello @Anonymous , thanks for reaching out.

The Fabric region is West Europe, I detected the issue on Wednesday. As far as I remember I accessed the notebooks successfully on Tuesday, on Monday everything was definitely fine.

Hi @JIlicGrECo 
This looks like an intermediate issue. Please try after sometime and let me know if the issue still exists.

Thanks.
