Hi Troy,

Thank you for reporting the error. We fixed an error with very similar stack couple days ago and the fix should be in the next beta.

Would you please verify that it fixes your case too?

This was resolved with the 3.8.0.251 version, will verify with 258 also.

Good to hear it!

Thanks a lot, Troy!
