You need to install opentelemetry-api==1.12.0rc2

[truekonrads]

Hello. I can confirm that installing

I can confirm that this works. Is it worth bumping up the dependency on wsgi to >=1.12.0rc2 and also opentelemetry-api=1.12.0rc2 needs opentelemetry-sdk of same or greater version

[srikanthccv]

Yes, the dependency version needs to reviewed.

@truekonrads we have released 1.12.0 for core components so pip should find that compatible version unless explicitly pinned to specific version. And the 0.33b0 requires the minimum version of 1.12 so this won't be in that version. I am going to close this issue.
