Catalog items requests on Service Portal are not submitting.

The same catalog item works when I click 'Try it' but it freezes and doesn't submit on Service Portal.

This is the error message I see when I inspect the page:

We recently moved all the Service Catalog items to Service Portal and there is a problem in submitting some forms and when I click 'Inspect' on the web page, I find this error. I'm not able to find the reason behind this.

Have you created a new catalog item for the portal to ensure this works as required?

Also - can you put up the configuration of your catalog item, it may have some config that isn't supported in the Portal.

Here is the catalog item

It doesn't have any client scripts, just a UI policy.
