Originally created by @maelp on GitHub (Apr 8, 2025).

Seems that at https://github.com/Dokploy/templates/blob/main/blueprints/supabase/template.toml#L30 we look for JWT_EXP but the env var seems to be defined as JWT_EXPIRY(?) https://github.com/Dokploy/templates/blob/main/blueprints/supabase/template.toml#L30

Also it's weird that the ANON_KEY and SERVICE_KEY are hard-coded? aren't they supposed to be created from the JWT_SECRET using something like

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.12"
# dependencies = [
#     "click",
#     "pyjwt",
# ]
# ///

@click.argument("b64_key")
def generate_tokens(b64_key):
    """
    Generate ANON_KEY and SERVICE_KEY using a base64-encoded secret key,
    and validate them to ensure correctness.
    """
    try:
        signing_key = b64_key  # base64.b64decode(b64_key, validate=True)
    except Exception as e:
        click.echo(f"❌ Invalid base64 key: {e}")
        return

    now = int(time.time())
    future = now + int(timedelta(days=365.25 * 100).total_seconds())  # 1000 years

    def make_token(role: str) -> str:
        payload = {"role": role, "iss": "supabase", "iat": now, "exp": future}
        headers = {"alg": "HS256", "typ": "JWT"}
        return jwt.encode(payload, signing_key, algorithm="HS256", headers=headers)

    def validate_token(token: str, role: str):
        try:
            decoded = jwt.decode(token, signing_key, algorithms=["HS256"])

        except InvalidTokenError as e:
            click.echo(f"❌ {role.upper()} token is invalid: {e}")

    anon_token = make_token("anon")
    service_token = make_token("service_role")

Recently a new template was implemented, and the old template was corrected, you can try it and check if you still have this problem.

So let's close this for now
