@ofaurax can you also include a few more fixes - I missed this in the previous PR,
create another PR if necessary,

• return error instead of fmt.Println,

bmclib/providers/redfish/tasks.go

Line 50 in 1f97b35

fmt.Println(err)

bmclib/providers/redfish/tasks.go

Line 152 in 1f97b35

fmt.Println(err)

• remove empty line,
  

  bmclib/providers/redfish/tasks.go

  Line 126 in 1f97b35

• else block can be removed,
  

  bmclib/providers/redfish/tasks.go

  Line 153 in 1f97b35

  } else {

err = json.Unmarshal(data, &status)
if err != nil {
	return nil, err
}
	
task = &gofishrf.Task{
	TaskState:  gofishrf.TaskState(status.TaskState),
	TaskStatus: gofishcommon.Health(status.TaskStatus),
}

return task, err
