That’s going to be an issue with the API, or the how the request is formatted.
Not a Postman issue per se. I can only suggest reviewing the API specification to check how the queries need to be crafted.
If its not returning data, the API should really return a status code of “204 - no content” rather than 200 ok. It doesn’t look like that request timed out when it probably should have. (Which is another status code again).
