Hi Team,

We are trying to send the data from jaeger to Elastic APM using the jaeger agent.

We are trying as per the elastic documentation. We are using below config.

```auto
args:
  - --reporter.grpc.host-port=<apm-endpoint:8200>
  - --reporter.grpc.tls.enabled=true
  - --agent.tags="elastic-apm-auth=Bearer <secret-token>"

```

We are getting an error while running jaeger.

"msg":"Could not send spans over gRPC","error":"rpc error: code = Unauthenticated desc = authentication failed: missing or improperly formatted Authorization header: expected 'Authorization: Bearer secret\_token' or 'Authorization: ApiKey base64(API key ID:API key)'"

Could you please hep us with this.

Solved by changing agent.tags with jaeger.tags.

```auto
args:
  - --reporter.grpc.host-port=<apm-endpoint:8200>
  - --reporter.grpc.tls.enabled=true
  - --jaeger.tags=elastic-apm-auth=Bearer <secret-token>

```
