>                 URL: https://issues.apache.org/jira/browse/TOREE-522
>             Project: TOREE
>          Issue Type: Bug
>          Components: Kernel
>    Affects Versions: 0.4.0
>         Environment: Both Spark 2.4.x and 2.2.x
> The version of the notebook server is: 6.0.3
> The server is running on this version of Python:
> Python 3.7.6 (default, Jan  8 2020, 19:59:22) 
> [GCC 7.3.0]
> Current Kernel Information:

>
> We have noticed that since the python package was released, all of our images that were build after 0.4.0 was released were not reporting errors in the notebook UI when running broken code.
>  
> What happens:
> 1. Open a Toree - Scala notebook
> 2. Type some random broken code
> 3. As far as the UI is concerned, it has ran successfully and no error was reported to the user.
> See screenshot `notebook-no-error-0.4.0.png`
>  
> Inspecting the network requests, I can see that the error does come back from the API, but the UI is not handling it correctly. See screenshot `f12-toree-channels-api.png`
>  
> Reverting back to 0.3.0 release works fine as per `notebook-versions.png` screenshot
>  
> Let me know if you need more details
