Google Translate API returns 502 error

I am trying to configure Google Translate api as a REST api data source. The api requires using POST and I have verified it works properly in both Rapid API ( and Postman ( Regardless of all t’ve tried, I keep getting 502 errors. I suspect the issue may be Record Properties object. Can the Record Properties object be suppressed? The error message returned is:

*Error: JSON error response from server: {"messages":"The API is unreachable, please contact the API provider","info":"Your Client (working) ---> Gateway (working) ---> API (not working)"}.status: 502*
