ошибка исключения при вставке данных формы vue. js в sql

Question

При вставке данных формы консоль пропускает ErrorException:

Преобразование массива в строку в файле E: \ laragon \ www\Project1 \ src \ api \ v1 \ vendor \ laravel \ framework \ src \ Подсветить \ Support \ Str. php.

Может кто-нибудь помочь мне в этом.

Мой код

 createRecord() {

        this.$vs.loading();


          jwt.createLeads(this.newRecord).then((response) => {

            this.$vs.loading.close();

            this.$vs.notify({
                title: 'Success',
                text: response.data.message,
                iconPack: 'feather',
                icon: 'icon-alert-circle',
                color: 'success'
            });

          //  response.data.leads['user'] = [];
            this.$store.dispatch("userManagement/upsertToState", { type: "Leads", data: response.data.leads });

            this.newRecord.leadtype = this.newRecord.first_name = 
   this.newRecord.last_name = this.newRecord.email_id = 
   this.newRecord.phone_number =
   this.newRecord.location = this.newRecord.postcode = 
   this.newRecord.lead_address = this.newRecord.gender = 
   this.newRecord.lead_source =
   this.newRecord.required_sub = this.newRecord.teach_mode = 
   this.newRecord.location_pref = this.newRecord.lead_frequency = 
   this.newRecord.session_duration = this.newRecord.pref_days = 
   this.newRecord.pref_time_slot = this.newRecord.tutor_pref = 
   this.newRecord.lead_owner = this.newRecord.notes = ''
           //   this.newRecord = ''

        }).catch((error) => {
            console.log(error)

            this.$vs.loading.close();


            this.$vs.notify({
                title: 'Error',
                text: 'There was an error creating the Lead',
                iconPack: 'feather',
                icon: 'icon-alert-circle',

            });
        });

    },
