I'm attempting to pull data from an API for machine records, the API json file with basic auth and just the url works fine in Postman, but when i try and recreate it as an HTTP action in my Flow it always returns with the error "The specified URL cannot be found." but when copying the url and opening it in another webpage the expected information is displayed. I've tried encoding the URL but that returns the "The provided 'Http' action URI '*sanitized*' is not valid.
There is no local path being referenced and the URI is valid. Can anyone please help? Is this a Header issue? the Postman script has no headers.
See images below of flow and results (I have confirmed that the username and password are correct.
