peteshea We apologize for the long wait for this issue! We have fixed this issue in 4.2.21-beta. However, at this time, not all of the official runtimes we offer support 4.2 features, so you may not be able to start using 4.2-beta in your project yet. If you are in a hurry and still want to roll back to 3.8, we are happy to help with any questions you may have.
