Get server response from Collector after sending data to backend

[oulfik]

I have currently configured my Otel Collector to send traces data from the adservice (Otel-demo service) to AppDynamics over a proxy. My problem is that AppDynamics doesn't show any ingested data in the Otel section (No Data available). The collector logs show no errors. Is there maybe an option to log the server response? I tried the zpages extension but it wasn't helpful. Currently I am only getting a generic debug message in the collector logs:

2023-10-04T12:39:03.931Z	debug	otlphttpexporter@v0.80.0/otlp.go:116	Preparing to make HTTP request	{"kind": "exporter", "data_type": "traces", "name": "otlphttp", "url": "https://some-agent-api.saas.appdynamics.com/v1/traces"}

Here is the complete collector logfile:
