from the start of the function up to this point it's the same code as in getTrace. Please move it to parseGetTraceParameters helper

Actually, URIs are different:

  • this is /api/traces?traceID=1, with a ?
  • the other is /api/traces/traceID=1, with a / in the same position

These are handled by different handler methods
