Brief summary
When investigating an error running a test I fund this message in the controller's log:
2024-08-28T16:57:38Z ERROR controllers.TestRun unable to marshal: `` {"namespace": "default", "name": "mytest", "reconcileID": "0f346969-ff9a-4e00-bf96-22c3ff880675", "error": "unexpected end of JSON input"}
github.com/grafana/k6-operator/controllers.inspectTestRun
/workspace/controllers/common.go:111
Looking at the code I found an unhandled error when reading logs from the pod (line 104) that can be hiding the root cause of this error:
102 buf := new(bytes.Buffer)
103 _, returnErr = io.Copy(buf, podLogs)
104 if err != nil { <--- this should be returnErr
105 log.Error(err, "unable to copy logs from the pod")
106 return
107 }
108
109 if returnErr = json.Unmarshal(buf.Bytes(), &inspectOutput); returnErr != nil {
110 // this shouldn't normally happen but if it does, let's log output by default
111 log.Error(returnErr, fmt.Sprintf("unable to marshal: `%s`", buf.String()))
112 }
