Can't find any podcast

[N4PSTER013]

I'm trying to search for a podcast using the Spotify API's endpoint: https://api.spotify.com/v1/search?q=nerdcast&type=show, following the documentation. The issue is that when I use Postman, the response returns status 200 but 'items' is an array filled with null values ([null, null, null...]). Strangely, when I use the request sample from the documentation, it works perfectly and returns a 20 podcasts. I considered authentication issues, but when I search for an artist using https://api.spotify.com/v1/search?q=coldplay&type=artist, it works fine in both Postman and the request sample section. So, why does the response differ when searching for podcasts?
