Jwt Token Generation and rate limiting

My flutter app (frontend) need to generate a jwt Token to be sent as Auth header bearer token with every request it sends to my backend which my backend will now use the token to get the user.

If the user exists, then the request is authenticated, and if not, it's refused at the backend.

Now I'm getting general rate limit error for endpoint that has to do with createJwt on appwrite on my flutter side.

What's the solution?

And could you suggest a better approach to the jwt Token creation and verification.
