It seems , Debug mode and running server in separate thread are n= ot compatible in Flask. And for Debug mode reloader need to be disabled for= such case. Othewise it give error. I've modified code to disable reloa= der in debug mode.

This problem only affects desktop runtime.

thanks and regards,

Ok, in that case, probably it's broken. Error mean, it doesn't like= running python code in separate thread.

The desktop runtime hasn't been tested in months afaik, so it's ent= irely possible something is broken at the moment. It is only PoC code right= now.

Hi,

I'm trying to pgAdmin4. I'm able to run pgAdmin4.py in python shell= . And server runs.And able to access using browser.
Then I tried running desktop application, it throws following error,

Traceback (most recent call last):

I can see what error says. As Qt application spawns separate thread to run = server, which apparently is not allowed.
Am I missing something ?
Have you created config_local.py?
