<img
  :height="$q.screen.gt.md ? '172px' : '148px'"
  :src="course.course.icon?.thumbUrl || course.course.icon?.url"
  :width="$q.screen.gt.md ? '172px' : '148px'"
  onerror="this.src = '/lk/img/no-image.svg'"
/>

<q-img
  :height="$q.screen.gt.md ? '172px' : '148px'"
  :src="course.course.icon?.thumbUrl || course.course.icon?.url"
  :width="$q.screen.gt.md ? '172px' : '148px'"
  onerror="this.src = '/lk/img/no-image.svg'"
/>

Furthermore, there already is the error event too. But events are attached like this: <q-img @error="handler" not <q-img onerror="handler".
