I have a small backend. Some of my methods give a response of 404 (for example, the user was not found) or 400 (request parameters error). Similarly, there is a small frontend. It intercepts all errors as needed and works quite successfully.
The only annoying thing is that when we get a response that is quite correct for frontend, from the backend, on the browser console, we get an error message like:
How to suppress this output?
Or will it disappear by itself if I switch from the "Development" mode to "Prod"?
