Something I forgot to note. Nicegui 1.4.8 and fastapi 1.0.8 does not have this problem. |

Strange. Do you see the notification popup when using @ui.page('/')
def index():
ui.button('click me', on_click=lambda: ui.notify('It works!'))Do you see any interesting in the javascript console? |
|
@aca-trevor-winn What do you mean with FastAPI 1.0.8? Its latest version is 0.112.1. |
No, I just tested and the notify did not work and nothing in the logs except pkg_resource being deprecated
When upgrading nicegui past 1.4.8 it requires fastapi >1.0.8. I was just stating the Fastapi version that was working with the nicegui version I was using. So opening up the consoles network panel I do see a websocket request being sent. I have also checked and onclick events are working. The UI is just not updating for some reason. I apologize for the late response, I posted this right before heading out for the weekend. |

Around version 1.4.8 we had some problems with an incompatibility with FastAPI 0.109.x, see #2354. Could you try upgrading to a newer NiceGUI version, e.g. 1.4.37? Or do you rely on FastAPI 0.108.x? |

What I meant was NiceGUI 1.4.8 DOES work but any version greater than that doesn't. Here is the code I am using to test: from fastapi import FastAPI
from nicegui import ui
app = FastAPI()
def onclick():
print('clicked')
ui.notify('It works!')
@ui.page('/')
def index():
ui.button('click me', on_click=onclick)
ui.run_with(app, storage_secret="secret")The print statement does execute but the notification never shows. This is also true if I make a change to a element and call .update, the element never does update. Here is the manifest file used for Posit: {
"version": 1,
"locale": "English_United States.1252",
"metadata": {
"appmode": "python-fastapi",
"entrypoint": "app"
},
"python": {
"version": "3.11.9",
"package_manager": {
"name": "pip",
"version": "23.1.2",
"package_file": "requirements.txt"
}
},
"files": {
"requirements.txt": {
"checksum": "63586e8f5039bccf552c70317574bae1"
},
"app.py": {
"checksum": "2238ee8f2f6cbf272898617fb579540b"
}
}
}
And here is the requirements.txt that it uses to spin up the environment: nicegui==1.4.37 I am wondering if this update from Posit is part of the issue:
Posit also had breakage due to the Starlette update. UPDATE: Looks like this Posit Connect update may have broken compatibility?

Have you tried setting the And I think you didn't answer my questions from above:
|
|
I have tried CONNECT_STRICT_ASGI. When set to true it throws errors. I can grab the error log for that if thought necessary. I have not tried updating to 2.0.1, I will do that and report back if anything changes. |
|
I have tested with Nicegui 2.0.1, with CONNECT_STRICT_ASGI true and false. Here are the logs for CONNECT_STRICT_ASGI true: Here are the logs for CONNECT_STRICT_ASGI false: |

Ok, we're out of ideas. This might be a problem specific to Posit Connect. Does anyone from the community have an idea what could be causing the issue? |
|
I downloaded nicegui source and added it to my test project, I can't use debug on the posit server but I am using print statements to find the source of the incompatibility. The loop for the client inbox is not running it seems, I am investigating further. |

Description

Minimal example:
In my local version the word changes to pineapple as expected, but on posit the word does not change. It seems the .update function isn't working possibly?
I am unsure as there are no errors thrown and nothing in the logs.
I have spent about 3 hours googling and trying to debug this, I am hoping I am missing something obvious.
