We are attempting to make a POST request to a Google Cloud service (basically to update a database with participant data in real-time). Because the API is external to Pavlovia, we are facing the following error:
Access to XMLHttpRequest at GCP DOMAIN HERE from origin ‘https://run.pavlovia.org’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
Is there any way to modify the Access-Control-Allow-Origin header on the Pavlovia server to allow calls to external APIs? It would be very helpful for more complicated experimental workflows where researchers are accessing AWS, GCP, etc. models and services.
