Python (not spark) Notebook exitValue issue
Is it a known issue that plain Python notebooks in Fabric don't return exitValue as expected?
I tried
```notebookutils.notebook.exit(json.dumps(json-object))```
as an alternative to the mssparkutils Ive been using with pySpark notebooks
but I get an empty string every time no matter how I set the notebook activity in my pipeline
Hi tobazan,
Explicit Output Management: Instead of relying on the exit() method, store the output in a predefined location that the pipeline can read, e.g., Azure Blob Storage or a SQL database.

Hi tobazan,
Thank you for reaching out to Microsoft Fabric Community Forum.
The issue likely arises because plain Python notebooks in Fabric do not fully support the notebookutils.notebook.exit() method for returning exit values, unlike PySpark notebooks. The output may not propagate correctly due to pipeline configuration or limitations in handling Python notebook exits within Fabric.
You need to ensure the pipeline is set up to capture outputs and consider using alternative methods like manual error handling or explicit output management within the notebook itself.
Please le me know if you have any additional questions.

not sure what you mean with "explicit output management within the notebook itself"
isn't that what Im doing with this line of code?notebookutils.notebook.exit(json.dumps(json_object))
as I see it, until this doesn't work as it does in pySpark notebooks there are very few use cases for plain python notebooks
Id prefer not to start a spark pool for lightweight tasks but python notebooks seem to need some more polish
anyways, I appreciate your quick answer and supportHi tobazan,
