Graph Explorer does not return Json formatted output

[CarlosGuadamuz]

Describe the bug

Graph Explorer is not returning Json formatted output.
Endpoints being tested so far:
https://graph.microsoft.com/v1.0/appCatalogs/teamsApps?$expand=*
https://graph.microsoft.com/v1.0/appCatalogs/teamsApps?$expand=appDefinitions
The same API works as expected if I pull Teams Apps information from other tenants.
My assumption is that this could be because the amount of information returned may varies. But I’m not sure.

To Reproduce
Steps to reproduce the behavior:

1. Go to (https://developer.microsoft.com/en-us/graph/graph-explorer)
   GET

https://graph.microsoft.com/v1.0/appCatalogs/teamsApps?$expand=*
https://graph.microsoft.com/v1.0/appCatalogs/teamsApps?$expand=appDefinitions

4. I get a 200 OK response.
5. The output is not easy to read because it is not Json formated.

Expected behavior
The output being returned in Json format.
