hello every one i was trying to use connect-flash with passport local but can not seem to find relevant info either on the docs and other sources,if any one can guide me on this and tell me what i went wrong ,thanks.And why does request to login-fail gives this error:-
ERROR is AxiosError: Request failed with status code 404
but when i test the route with rest client on vscode it responses perfectly like seen below.
also when i check the database right after i click submit on the route there will be two sessions stored consecutively one having the flash(the first) and the other not like this:-
session:
{"cookie":{"originalMaxAge":259200000,"expires":"2023-01-16T12:30:14.395Z","secure":false,"httpOnly":true,"path":"/"},"flash":{"error":["Incorrect password"]}}
session:
{"cookie":{"originalMaxAge":259200000,"expires":"2023-01-16T12:30:14.453Z","secure":false,"httpOnly":true,"path":"/"}}
why this is happening?
