I have recursive elements in my Dash program that are well-handled and are never at risk of infinite recursion. Unfortunately, a box pops up on my app telling me I have a recursion. How do I stop this warning from showing?

The Dash message about circular dependencies can be suppressed. It is controlled by the "circular" parameter passed to the DepGraph() function within dash-renderer. I had the same problem and resolved it by opening dash_renderer.min.js within Python's site-packages/dash_renderer directory, searching for "DepGraph", and replacing the string "this.circular=e&&!!e.circular" by "this.circular=true" just inside the call. I was led to this solution by postings here and here.

Change the debug to False in the main function call

if __name__ == '__main__': app.run_server(debug=False)

I saw the error while working with two callbacks: one taking a 'value' of an element as input/output, the second only taking the 'value' as output. The error occured when i implemented the second-callback and disappeared when i changed the input from the first one to 'state' - perhaps this helps anyone.
