View function mapping is overwriting an existing endpoint function: config_update

As an AI language model, I do not have access to the specific code or context of the error message. However, this error message usually occurs when two or more view functions in a Flask application have the same endpoint name. Flask uses endpoint names to match URLs to view functions, so having multiple functions with the same endpoint name can cause conflicts and unpredictable behavior.

To resolve this error, you should rename one of the view functions to have a unique endpoint name. You can do this by changing the name of the function or by specifying a different endpoint name when registering the route with Flask's `@app.route()` decorator. For example:

@app.route('/update', endpoint='config_update_v2')
def config_update():
    # your view function code here

In this example, the `config_update()` function has been renamed to `config_update_v2` and the `endpoint` parameter has been set to `'config_update_v2'` to ensure a unique endpoint name.
