Are you making a GET request to your server and adding those fields into the query params?

nope. i am making a post request

i am using formik and client side with fetch

Can you share your code?

do you want it in github ?

I don't see anything out of the ordinary, using the regular fetch call with POST and putting the user/pass in the body. Can you include a screenshot of what you're seeing

I'm thinking that OP has a form and it doesn't have preventdefault on event listener and as such, adds the query params to the url and reloads page

In react hook forma also happend

ahhhh probly add prevent default or something so it wont trigger a post or probly add POST method on form probly? it is weird

it is just like with that query appended when aubmitting form .

it sometimes do not show sometimes it shows
