A PR was made, something like this:
// next.js getServerSideProps
export const getServerSideProps = async (ctx) => {
const { valid, event } = await isValidEvent({
organizationSlug,
projectSlug,
probeSlug,
eventSlug,
userID: ctx.user?.id,
})
const currentEvent = {
id: event?.id,
locationId: event?.locationId,
monika: event?.monikaId,
alert: event?.alertId,
response: parseEventResponse(event?.response),
createdAt: event?.createdAt.toString(),
recoveredAt: event?.recoveredAt?.toString() || '',
location: event?.location,
}
return {
props: {
currentEvent,
},
}
}
The problem with that PR is that it's reading the optional event too many times. Furthermore, in this case since it's Next.js's getServerSideProps, it's better to check the existence of event and return notFound when it's null or undefined since the page component expects a valid event data.
