werkzeug routing builderror could not build url for endpoint profile did you mean index instead python

The error BuildError: could not build url for endpoint 'profile' usually occurs when the given endpoint name is not registered with the Flask application or when the endpoint name is incorrect.

To fix this error, make sure that you have registered the endpoint using the @app.route decorator and that the endpoint name is spelled correctly. You can also try specifying the full URL path of the endpoint instead of just the endpoint name.

For example:

@app.route('/profile')
def profile():
# code here

# Correct usage
url = url_for('profile')

# Incorrect usage (endpoint name not registered or spelled incorrectly)
url = url_for('profle')

If the error persists, it might be caused by a problem with the routing rules or the URL map. In that case, you can try debugging the routing logic and make sure that the correct endpoint is being called.
