I doing a learning project with actix and a local json database so this whole project may seem a bit strange but my problem is that I'm getting this error message:
thread 'actix-rt:worker:0' panicked at 'what the heck: Os { code: 9, kind: Other, message: "Bad file descriptor" }'
I don't understand why.
I have an endpoint "localhost.../signup" that is calling "post_signup" handler function.
The panic occurs in the function "update_user_index" when I'm trying to write to the file and I just don't get it.
File exists, filename and path is correct.
If I missed any relevant info, let me know.
