Hello @sharebear !

Just stumbled across your issue when I had the same problem as you did.

In your query, you use the default_zero function. It seems incompatible with the on_missing_data parameter (because you would never have no data with a default_zero).

Even in the interface, I can not create the monitor with these 2 settings: I get the same error message if I try to validate it. Though, that message could be a bit more explicit

Choosing one or the other fixed it for me.

Yeah, I understood the problem, the bug report here was that I was able to generate invalid Terraform through the export function. The export function generating invalid code broke the principal of least surprise for me.
