i want to save data in nativescript using API, but error JS: [Error: Network error: Converting circular structure to JSON] - api

Question

i want to save result in nativescript, but show error JS: [Error: Network error: Converting circular structure to JSON]
in list.vue i push the id from each button +/-. here is the code
confirm() {
// The result property is true if the dialog is closed with the OK button, false if closed with the Cancel button or undefined if closed with a neutral button.
this.duhmboh=[]
this.pageData.forEach((element,index) => {
if(element.qty>0){
this.duhmboh.push({
id:element.id,
guest: this.guests[index],
qty: element
})
}
});
this.duhmboh.forEach(element => {
console.log("DUMBOH",element)
});
this.$showModal(modal, {
props: {
tempData: this.duhmboh
},
fullscreen: false,
animated: false,
stretched: false,
dimAmount: 0.2,
dismissEnabled: false
})
},
and the modal.vue is like this
save(qty) {
if (this.is_saving) return
this.is_saving = true
var vm = this
this.$apollo.query({
query: gqlUseVoucher,
variables: {
id: this.pageData.id,
qty_used: qty
},
fetchPolicy: 'no-cache'
}).then((resp) => {
if (resp.room.AuthorizeVoucherUsingID) {
vm.is_saving = false
vm.$modal.close()
vm.$store.commit('setSuccess', 'Voucher breakfast berhasil divalidasi')
} else {
vm.is_saving = false
errorHandler(vm, null, 'Voucher breakfast tidak dapat digunakan')
}
}).catch((error) => {
vm.is_saving = false
console.log(error)
errorHandler(vm, error)
})
},
and i still cant click the button ssave. what should i do?
