@trivikr I changed the title to include a ! to mark this PR as a breaking change so it shows up as such in the changelog.

Please update the branch if you find the time to see if the build failures have been resolved. I think the TAV failures are resolved by #2628 and #2643 🙂

[trivikr]

Thank you @pichlermarc. I've rebased the changes.

The CI is failing though for the path which isn't updated

  1) MessageAttributes
       injectPropagationContext
         should inject context if there are available attributes:
     Error: expect(received).toBeGreaterThan(expected)

Test code which fails:

opentelemetry-js-contrib/plugins/node/opentelemetry-instrumentation-aws-sdk/test/MessageAttributes.test.ts

Line 84 in 6b4e532

expect(Object.keys(contextAttributes).length).toBeGreaterThan(5);

Execution https://github.com/open-telemetry/opentelemetry-js-contrib/actions/runs/12792793464/job/35664659517?pr=2623

I confirmed when debugging that propagation.inject is called but it has not impact on the contents of attributes
Source code

opentelemetry-js-contrib/plugins/node/opentelemetry-instrumentation-aws-sdk/src/services/MessageAttributes.ts

Line 81 in 6b4e532

propagation.inject(context.active(), attributes, contextSetter);

@blumamir @jj22ee Do you know what may be going wrong?
