            WARNING: GraphQL Custom validator registered: #{validator_name}
            Note that custom validators with I/O operations may fail unexpectedly due to GraphQL's default validate_timeout setting. Long-running I/O operations may not be killed halfway through, resulting in unpredictable behavior. See https://graphql-ruby.org/queries/timeout.html#validation-and-analysis for more information.
