Hello!
For now you could get unblocked by installing a 2.1 runtime. We're planning to release a new version of the CLI soon that supports 3.1 and newer runtimes.

Resolving this issue. If my workaround didn't unblock you then please re-open this issue!

We'll be shipping a new CLI this week that will work with 3.*.

Cheers,
Jake
