How to reproduce Deploy a https azure app service, web service

A code fragment


from taipy import Gui
import taipy.gui.builder as tgb
import os
from pages import productservices, edm, root
import taipy as tp

pages = { "/": root.root, "ProductServices": productservices.ProductServices, "EdmHandbookRag": edm.EdmHandbookRag }

tp_app = Gui(pages=pages)

if name == "main": tp_app.run(debug=True, use_reloader=True) # , async_mode='standalone' else:

Production mode, Azure Web Application runs the application with Gunicorn.

app = tp_app.run(run_server=False, port=8000, title="LLM", debug=True, ) #, async_mode='standalone'


- And/or configuration files or code:
    ```python
    ...

And/or Taipy GUI Markdown or HTML files

Expected behavior No errors

Fixed with custom startup cmd gunicorn -k "geventwebsocket.gunicorn.workers.GeventWebSocketWorker" -w 1 -b 0.0.0.0:8000 app:app ?

Thank you for the issue and its solution. We will make sure to update the doc accordingly.

I don't know if you use Taipy Core features with scenario and data management, but Gunicorn has limitations when using execution mode. You could use our command line interface (taipy run ...) to run Taipy.

I changed the port on the CMD and also in tp.run, still see the same issue.

FlorianJacta commented 3 days ago

Could you describe your issue and how did you produce the error? @swateek
