SIGWINCH ignored when trying to start a screen with the pexpect module

[StatTark]

I made an application with Python's flask module. I used the pexpect module in some functions but I get the SIGWINCH ignored error. The function does not work, it enters pexpect.EOF error directly. If anyone knows the solution, I would be glad if it helps.In the bottom line of the gunicorn error file, the / botbaslatma function, in other words, the function I use the pexpect module. SIGWINCH ignored. error and goes directly into pexpect.EOF.
