Describe the bug

Upgraded to dash 3.4.0. added hide_all_callbacks=True in Dash()

Expected behavior

it should work. But getting error TypeError: Dash() got an unexpected keyword argument 'hide_all_callbacks'
this is coming from check_obsolete in _validate.py
i am using uv as a package manager
Screenshots

NA

@biyani701 this parameter should be set in app.run().

[biyani701]

ok. i set that in run as suggested
app.run(debug=True, port=1951, host="localhost", hide_all_callbacks=True)

however, i am still seeing this big callback graph. What additional set-up do i need to do to effectively use this feature?

@biyani701 Are your callback functions of the clientside type? There is currently a small bug where clientside type callback functions cannot be hidden via the hide_all_callbacks parameter. This issue is being addressed in #3581 and should be fixed in version 3.4.1.

[biyani701]

i have a mix of both.
e.g.
@callback(
[
Output("capacity-customer-select", "options"),
Output("capacity-customer-select", "value"),
Output("capacity-program-select", "options"),
Output("capacity-program-select", "value"),
Output("capacity-project-select", "options"),
Output("capacity-project-select", "value"),
Output("capacity-jira-space-select", "options"),
Output("capacity-jira-space-select", "value"),
],
[
Input("capacity-refresh-btn", "n_clicks"),
Input("capacity-customer-select", "value"),
Input("capacity-program-select", "value"),
Input("capacity-project-select", "value"),
],
[
State("capacity-analytics-scope", "children"),
State("url", "pathname"),

prevent_initial_call=False

def populate_all_hiearchical_filters(

@biyani701 Can you try to reproduce this issue with another independent Dash application, similar to what I mentioned in #3579 (comment)

[CNFeffery]

@biyani701 Take my actual application as an example: https://github.com/CNFeffery/feffery-antd-docs

When hide_all_callbacks is not set:

After setting hide_all_callbacks=False, as far as I can observe, all the remaining callback functions are of the clientside type:

[biyani701]

@CNFeffery
Thanks for your quick response. I took your demo app and wrote my own demo app.
when hide_all_callbacks=True the clientside callbacks are appearing.
setting hidden=True in the client side callback like below hides the callback

clientside_callback(
"""
function(n_clicks) {
console.log('Clientside callback 2 - Notify button clicks:', n_clicks);
return 'Clientside 2: Notify clicked ' + (n_clicks || 0) + ' times';
}
""",
Output("clientside-debug-2", "children"),
Input("notify", "n_clicks"),
hidden=True,
)

[CNFeffery]

@biyani701 Are there any regular server-side callback functions that still appear in the callback graph after setting hide_all_callbacks=True?

[biyani701]

There were no server side callbacks visible. Only clientside callbacks were visible due to the bug that you mentioned above. hope the fix will come soon as setting hidden=True in each and every clientside callback will be a humungous effort in big complex apps.

[robertclaus]

Closing as a duplicate since the clientside callback behavior will be fixed seperately.
