Could you please share your configuration file?
Your issue seems to be similar to this: #27851 (comment)

[gyliu513]

@yantingqiu here are all the configuration file https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/examples/demo , I did not make any changes.

[yantingqiu]

@gyliu513 To enable the debug exporter, you need to ensure that the version of otel-collector is 0.86.0 or higher. Maybe you should consider updating the image version of otel-collector to be at least 0.86.0.

[gyliu513]

@yantingqiu it worked with 0.88.0 as the PR #28566

I'm going to close as it looks like this has been resolved, but please let me know if I've misunderstood. Happy to see things are working now!
