User response
Ensure that the URL you entered in the REST v2 Schema Discovery wizard is valid. To verify that a schema is valid, paste the schema URL into a web browser. If the XML content loads correctly in the web browser so that the XML content is visible, the URL is valid. If the URL is valid, the issue might be that the dependencies could not be resolved or the server could not be reached.
