Cell timeout after 5 mins

[tylerlekang]

System:
Windows 10
Conda 23.5.0
Python 3.8.16
matlab-proxy 0.10.0
jupyter-matlab-proxy 0.10.1
Matlab R2023a Update 5

(though I observed the issue with earlier versions of jmp)

Issue:
Cell "times out" after 5 mins, even though the code still runs:

I also see the following error in the Anaconda Prompt:

Desired Behavior:
On the exact same running Jupyter Server, if I select the python kernel there is no such issue:

Hoping this is just a setting that can be changed.

If not, please consider adding and/or addressing whatever issue is causing this undesired behavior. Thank you!

Hi @tylerlekang

Unfortunately, this is a timeout that is coming from our dependencies, viz: jupyter-server-proxy. We are actively working towards alternate ways of communication which should alleviate this issue.

Perhaps you can create a PR to change this hard-coded 300 to become a parameter in jupyter-server-proxy:
