Relay stopped working with error unknown variant 'spanOperations', expected 'span_operations'`

[holophil]

Environment

How do you use Sentry?
Sentry SaaS (sentry.io)

Which SDK and version?
Relay 21.4.1 (via dockerhub relay:latest)

Steps to Reproduce

Deploy relay 21.4.1 in managed mode.

Expected Result

Relay executes without error logs.
Relay can fetch project states successfully (projectsconfig endpoint).

Actual Result

Relay logs the following error
ERROR: error fetching project state <redacted>: unknown variant 'spanOperations', expected 'span_operations'

It seems that relay is not relaying any events to sentry SaaS anymore.

Probably caused by recent change in the projectsconfig endpoint release to sentry SaaS without releasing related change on sentry relay.

Thanks and sorry, we're reverting the change at getsentry/sentry#26082
