Test run fails with panic: runtime error: invalid memory address or nil pointer dereference with an wrong Tracing Backend

[danielbdias]

Describe the bug

I'm running the example located on https://github.com/kubeshop/tracetest/tree/main/examples/datadog-propagation with:

cd examples/datadog-propagation
TRACETEST_API_KEY=my-api-key docker compose -f ./docker-compose.step4.yaml up -d

With a tracing backend set by mistake to a tempo backend with address tempo:9095.

Next, I'm creating a test like this as ./tracebased-tests/otel_sdk_instrumented_api_to_datadog_instrumented_api.yaml:

type: Test
spec:
  id: CdhJp_xIR
  name: OTelSDK-instrumented API to Datadog-instrumented API
  trigger:
    type: http
    httpRequest:
      method: GET
      url: http://api-otel:8080/remotehello
      headers:
      - key: Content-Type
        value: application/json

When I run the following command:

tracetest run test -f ./tracebased-tests/otel_sdk_instrumented_api_to_datadog_instrumented_api.yaml

I'm receiving the following error:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x162aeec]
