No token passed in. Token={token}

Error message

No token passed in. Token={token}

What it means

Defensive guard in the PrismaClient find_unique path for key verification: the query type was resolved to 'key' but the token value itself is None, so there is no credential to look up. Indicates a malformed internal call rather than a bad key; the Token=None is echoed in the message.
