I'm working on fetching data with React and graphql and render it with react/pdf-renderer.
I use renderContent but it gives me this error. What I'm doing wrong?
Uncaught TypeError: Cannot read properties of undefined (reading 'bookingConfirmationNumber')at renderContent
Below is my code
const renderContent = () => {
const hotelDetails: HotelDetailsType = data.getHotelDetailsByIds.items[0]
return (
<PDFViewer>
<Document>
console.log(hotelDetails.bookingConfirmationNumber)
<Page>
<View>
<Text>{hotelDetails.bookingConfirmationNumber}</Text>
<Text>{hotelDetails.hotelName}</Text>
<Text>{hotelDetails.address}</Text>
<Text>{hotelDetails.hotelContactNumber}</Text>
<Text>{hotelDetails.guestName}</Text>
<Text>{hotelDetails.guests.adults}</Text>
<Text>{hotelDetails.guests.children}</Text>
</View>
</Page>
</Document>
</PDFViewer>
)}
Here is my schema
export type HotelDetailsType = {
bookingConfirmationNumber: string
hotelName: string
address: string
hotelContactNumber: string
guestName: string
guests: HotelGuestsType
}
I tried optional chaining, it renders the PDF component but data were not being fetched and Query is working fine in Graphql. Any inputs and resource to read on is highly appreciated.
Thank you.
Update:
hotelDetails is indeed sending undefined. But I still can't figure out why. If I query directly in graphql it is working. Please see below additional info.
const InvoicePDFModal: React.FC<InvoicePDFModalProps> = ({ hideModal, hotelBookingId }) => {
const profile = useSelector(selectedCustomerProfileSelector)
const { data, loading, error } = useQuery(GET_HOTEL_DETAILS_BY_IDS, {
variables: {
hotelDetailIds: [hotelBookingId],
customerId: profile.userId
}
})

I really appreciate the help guys. Thank you so much.
hotelDetails is resulting in undefined simply because data.getHotelDetailsByIds.items[0] (and data.getHotelDetailsByIds in the previous version of your question) is undefined. When you inspect data, you should see the issue.
It looks like data.getHotelDetailsByIds returns empty array. So, data.getHotelDetailsByIds.item[0] is undefined.
