Sign In Button Remains Disabled When Logging in with Email/Password on Langfuse Self-Hosted

[tubone24]

After updating to Langfuse v.2.83.0, the Sign In button remains disabled even when entering the correct Email/Password, as shown in the attached screen.

Upon reviewing the code related to the Sign In button, the conditions for disabling it are:

                    disabled={
                      env.NEXT_PUBLIC_TURNSTILE_SITE_KEY !== undefined &&
                      turnstileToken === undefined
                    }

Since the TURNSTILE_SITE_KEY is not set in this environment, the button should be enabled.

You can find the relevant code here:

langfuse/web/src/pages/auth/sign-in.tsx

Lines 426 to 430 in 02e5c01

	disabled={
	env.NEXT_PUBLIC_TURNSTILE_SITE_KEY !== undefined &&
	turnstileToken === undefined
	}
	>

The following environment variables are set in the container:

ENCRYPTION_KEY
HOSTNAME
NEXTAUTH_SECRET
NEXTAUTH_URL
SALT
DATABASE_URL

Hey @tubone24, I'm here to help you with any bugs, questions, or contributions! Let's work together to solve this issue.

The issue with the Sign In button remaining disabled in Langfuse v.2.83.0 is likely due to the condition:

disabled={
  env.NEXT_PUBLIC_TURNSTILE_SITE_KEY !== undefined &&
  turnstileToken === undefined
}

Since NEXT_PUBLIC_TURNSTILE_SITE_KEY is not set, the button should indeed be enabled. However, ensure that turnstileToken is actually undefined. Also, check if there are other conditions affecting the button's state, such as the form submission state (credentialsForm.formState.isSubmitting) which could also disable the button if the form is in the process of submitting ^[1].
