This is the same error we received in a recent release, #1765, but as far as I can tell, everything was released successfully despite this command failing.

We didn't want to release the opentelemetry-exporter-otlp as part of this release, so I'm not sure why a release of that gem was attempted.

i'll take a look!

Had a small amount of time to look into this, where I left it is it looks like the toys gem is being optimistic when determining which gems to release https://github.com/dazuma/toys/blob/17ed449da8299f272b834470ff6b279a59e8070b/.toys/release/.lib/release_utils.rb#L436

At a glance This would explain the erroneous attempt to release opentelemetry-exporter-otlp (and subsequent 422 response from GitHub api) even though it only has files changed related to opentelemetry-exporter-otlp-metrics. iiuc, GitHub api returns a 422 if you try to release a tag that's already been released.
