I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @lschmierer, thanks for the report. I was able to replicate the issue using SDK version 9.0.0-beta.1.

This issue has been raised and discussed with the team. I will keep this thread posted for any updates.

Isn’t this a duplicate of #4789 - only mentioning that it also affects 9 beta.

[lschmierer]

@akauppi #4789 has an incorrect dependency warning while this is about missing missing peer dependencies.
#4789 appears to happen on npm@7 while this is on npm@6.

Npm@7 automatically installs peer dependencies while npm@6 doesn’t.

The warnings should be gone in 9.0.0-beta.2.
