How to fix incorrect output to the server console?

Question

Python

Colleagues, good afternoon.
Installed pycharm 2019.4 on another machine. Dropped my project. I started the flask server and now the following entries are displayed in the console when accessing the server:

127.0.0.1 - - [19/Feb/2020 15:54:49] "?[31m?[1mPOST /api/auth HTTP/1.1?[0m" 401 -

Although previously there were no these characters at the beginning and at the end of the string enclosed in quotation marks (before the verb and before the response code).

Please let me know if you have come across something like this.
Thank you.
