Cannot read json data from API

[Gin]

Hi Team.

Now Im trying to call following api from adalo app.

http://ergast.com/api/f1/constructors.json

When i call this api from Postman, it returns 200.

But in adalo, following error occur.(I will attach screenshot)

I set the value, MRData / Constructors as resultKey but error did not change.

How should I fix it?

Thanks,
