Version: 3.233.0 running preview fails with the following exception. 3.232.0 works fine. Looks like a potential parsing error as we have some resource properties that we ignore that contain hyphens ('-').

failed with an unhandled exception:

Thanks for the report; I notified the core team to take a look

Thank you!

yeh this looks like an unintended regression, we'll get it reverted and a patch release out
