Helm "opentelemetry-operator" - cannot enable auto instrumentation for Golang

[diegocejasprieto]

That's simple: I cannot enable auto instrumentation for Golang using Opentelemetry Operator deployed by Helm. I get this error message

invalid argument "autoinstrumentation.go" for "--feature-gates" flag: no such feature gate "autoinstrumentation.go". valid gates: [operator.collector.default.config operator.collector.targetallocatorcr operator.golang.flags operator.observability.prometheus operator.sidecarcontainers.native operator.targetallocator.fallbackstrategy operator.targetallocator.mtls]

This is an extract of my operator configuration declared in values.yaml:

manager:
image:
repository: ghcr.io/open-telemetry/opentelemetry-operator/opentelemetry-operator
tag: ""
collectorImage:
repository: otel/opentelemetry-collector-k8s

featureGates: "autoinstrumentation.go"

Note: I have already deployed a custom resource of instrumentation which works properly, it's just the operator that refuses to auto instrument it with Golang

UPDATE: I just found a way to enable it by passing this argument in the "extraArgs" section of the manager. I don't know if this is the proper way to do it, but I couldn't find any other way to do so (this procedure also works when you deploy the Opentelemetry collector manually)

manager:
    extraArgs: [--enable-go-instrumentation]
