Issue running the adapter : Http Error: 404 Client Error: Not Found

[achrafcei]

Hello,
On a new project, I'm testing if I can use this adapter for my workloads, but when I try to just debug the project, I hit a snag :

Traceback (most recent call last): File "/home/unix/dbt/bin/dbt", line 8, in <module> sys.exit(cli()) File "/home/unix/dbt/lib/python3.10/site-packages/click/core.py", line 1157, in __call__ return self.main(*args, **kwargs) File "/home/unix/dbt/lib/python3.10/site-packages/click/core.py", line 1078, in main rv = self.invoke(ctx) File "/home/unix/dbt/lib/python3.10/site-packages/click/core.py", line 1687, in invoke with sub_ctx: File "/home/unix/dbt/lib/python3.10/site-packages/click/core.py", line 466, in __exit__ self.close() File "/home/unix/dbt/lib/python3.10/site-packages/click/core.py", line 595, in close self._exit_stack.close() File "/usr/lib/python3.10/contextlib.py", line 584, in close self.__exit__(None, None, None) File "/usr/lib/python3.10/contextlib.py", line 576, in __exit__ raise exc_details[1] File "/usr/lib/python3.10/contextlib.py", line 153, in __exit__ self.gen.throw(typ, value, traceback) File "/home/unix/dbt/lib/python3.10/site-packages/dbt/tracking.py", line 493, in track_run yield File "/usr/lib/python3.10/contextlib.py", line 561, in __exit__ if cb(*exc_details): File "/usr/lib/python3.10/contextlib.py", line 142, in __exit__ next(self.gen) File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/factory.py", line 237, in adapter_management cleanup_connections() File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/factory.py", line 196, in cleanup_connections FACTORY.cleanup_connections() File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/factory.py", line 124, in cleanup_connections adapter.cleanup_connections() File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/base/impl.py", line 261, in cleanup_connections self.connections.cleanup_all() File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/fabricspark/connections.py", line 203, in cleanup_all livySession.disconnect() File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/fabricspark/livysession.py", line 489, in disconnect if __class__.livy_global_session.is_valid_session(): File "/home/unix/dbt/lib/python3.10/site-packages/dbt/adapters/fabricspark/livysession.py", line 195, in is_valid_session self.connect_url + "/sessions/" + self.session_id, TypeError: can only concatenate str (not "NoneType") to str

It seems not to be able to start a session, is the api available to be used ?

Hello,
Any possible answer for this ?

[jcvdodson]

Have you applied for the Livy Public Preview? If your workspace/lakehouse hasn't been approved for Livy's Public Preview, then the adapter won't be able to connect.

[achrafcei]

Is there a link to apply for the public preview?

@jcvdodson I am getting this same issue, is this because livy needs to be explicitly turned on? If so how can we go about obtaining access to the livy preview?

Find any solution ?

I'm too unable to establish a connection to Livy endpoint with error 404 by using the dbt-fabric adapter.
Is there a solution for this?
