Hi @ServicenowDev19 

If the Catalog Client Script in not working in the portal. Please check the following steps.

1. Open the Catalog Client Script, and select UI action as Both or ALL so it will run on portal too.

2. Verify that script runs when click on the "TRY IT" on the catalog item in the instance.
