I had thesame issue but createing the formData with the formData constructor helped as so.

methods: {
    onSubmit () {
      const asyncLog = async (asyncLog) => {
        try {
           const formData = new FormData()

           formData.set('names', this.name)
           formData.set('email', this.email)
           formData.set('phone', this.phone)
      
          await this.$store.dispatch('forms/callback', formData)
        } catch (e) {
          throw e
        }
      }
    asyncLog()
    console.log(asyncLog())
    }
  }
