[jcsrb]

Running Kubernetes in Google Cloud I upgraded from 3.10.1 to 3.11 and started receiving failed to validate metadata errors

[ElasticAPM] APM Server responded with an error:

Thank you for reporting this.

This is a bug in APM Server (elastic/apm-server#4142). It is fixed in 7.10.0 which will be released soon.

I'll make a quickfix release of the agent to fix compatibility until then.

Let me know if v3.11.1 fixes this for you and thanks again for reporting it.
