API call in Catalog not executing - returning: TypeError: Failed to fetch

When trying to execute API calls via Tyk catalog I get a return of TypeError: Failed to fetch

Not sure what’s wrong, I can make the calls via Postman, where I can see them logged properly in Tyk. When calling from the catalog I see nothing in Tyk logs, so I’m guessing it’s not even executing the request.

Here’s a link to the documentation: https://particlehealth.cloud.tyk.io/portal/apis/5de6cc682e835c0001db9b0d/documentation/

FYI this was fixed by updating the endpoints to the tyk endpoints in the swagger json
