Maximum call stack size exceeded

[smokedlinq]

Bug description

With an API operation that has a schema with a discriminated type, the portal will show the operations listing but not the operation details. In the developer tools, the console shows the following error: Maximum call stack size exceeded

I have a support case (2309010040007100) open for quite a while without much progress.

Full error from browser console:

Uncaught (in promise) RangeError: Maximum call stack size exceeded
