SDK Release Checklist

• Have you added an integration test for the changes?
• Have you built the library locally and made queries against it successfully?
• Did you update the changelog?
• Did you bump the package version?
• If endpoints were removed, did you manually remove the corresponding files? (this should be rare)
• For breaking changes, did you plan for the release of the new SDK versions and deploy the API to production?

@holtbp did you generate from client-code-generation.

This (the failing test on the SDK) is very very not urgent, so feel free to leave this be for now.

Yes, generated and it seems maybe my pre-commit hook did some formatting here via black locally. I've put this on the back burner atm.
