Google Cloud Document OCR Connected System: Unable to get response on "Wait for Results"


As seen in the image below, when I have Wait for Results checked the request will execute and generate a JSON file with the output on the Google Cloud Storage bucket but as a response I get :

Not sure if I missed any permissions anywhere. When I perform Format OCR Results on the output JSON file, I get the Appian Object response.

Appian 19.3 and Google Cloud Document OCR Connected System Version 1.

Thank you.
