Unable to establish connection to Livy endpoint with error 408

[nixent]

Trying to materialize a model with the dbt-fabric adapter. It fails to establish connection to Livy endpoint and times out at create_session

Error message: Http Error: 408 Client Error: Request Timeout for url: https://api.fabric.microsoft.com/v1/workspaces/{workspace_id}/lakehouses/{lakehouse_id}/livyapi/versions/2023-12-01/sessions

Call to other endpoints, like List tables works fine.

Is there any configuration that needs to be done to make it to work?

[jcvdodson]

Are you always getting this error? There shouldn't be any additional config needed.

@jcvdodson no, now with same code I'm getting error 404

[jcvdodson]

Hmm, that's interesting. Have you double-checked your workspace_id and lakehouse_id in the profiles yml?

[nixent]

yes, I have checked connection by calling List tables as it includes both workspace_id and lakehouse_id, and it works fine.

I learned about the dbt-fabricspark adapter from dbt channel on Slack where @prdpsvs mentioned that Livy endpoints are in private preview and I should contact our Microsoft account team to sign up for the preview which I have done. Could be that something else needs to be done to activate it for our Fabric capacity.

If you are able to create Lakehouses, you should be okay as far as Fabric capacity. Livy might have additional restrictions, but given that Synapse also uses Livy, you should also be good there.

If you'd like, you can email me at t-jdodson@microsoft.com and I can see if I am able to reproduce this issue.

Have you signed up for the Livy Public Preview?
