[Vuejs]-VueJS won't display data from Express API

async searchGroups (params) {
   await axios.get('groups/search?text=' + params.terms)
}

you are not returning anything from this function ?!

Try to return the result of this async function (searchGroups)

async searchGroups (params) {
  return await axios.get('groups/search?text=' + params.terms)
}
