Invoking OIC REST API from Service Connection returns 404 error

If you are using version 119 or later of the Chrome browser, you might see the following error when trying to create a Service Connection to OIC integrations (using the "Select from Catalog") option:

"Error: "Network Error Unable to read the integrations from [vb-catalog://backends/ics/ic/api/integration/v1/integrations]. Please check the settings for Integration Applications and verify that Integration Applications server is working."

The reason for the error is that starting with version 119, the Chrome browser treats cross-domain redirects and CORS differently than earlier versions.

If you encounter the error, navigate to the "Integration Applications" backend and change the Connection Type to "Always use proxy, irrespective of CORS support" to eliminate the CORS issue.
