Sorry for the trouble < hallowed beach 15050> We added some extra type checks in the Python SDK in v2 9 0 which mistakenly errors when some internal values are returned from the engine during previews The issue has been addressed in and should be released soon In the meantime you can pin to earlier versions of the `pulumi` and `pulumi aws` packages `pulumi` `2 8 2` and `pulumi aws` `3 1 0`

This looks like a bug in the Datadog provider The same issue happens in C programs it s just now showing up in Python due to the type checks that were added During previews `thresholds` is coming back as a list containing a map but it is expected to be just a map I ve opened <https github com pulumi pulumi datadog issues 73> and am looking into it
