JSON data adapter doesn't read data from the URL

I have an API working and can get data from it on POSTMAN using the correct authentication details and parameters of the GET request. The output is as follows:   

 

 

 

 

 

 

 

 

 

 

 

 

 

But when I set the same parameters in the GET request in JSON adapter, it returns the key count but doesn't return any data, neither in the data preview option nor in the report.
Here is the request:

I am unable to get to know the cause of the error as if there was a problem on the API side, it would not have returned anything to the POSTMAN request as well and nothing to the JASPER data adapter. What might be causing the issue? Thanks a lot for your time.
