I'm attempting to store data on the Postgres database deployed. My route.ts has two endpoints as following <code>app/guests/route.ts</code> ``` // File: src/app/api/guest/route.ts import { NextRequest, NextResponse } from 'next/server'; import prisma from '../../../lib/prisma'; export async function GET() { try { const guests = await prisma.guest.findMany(); return NextResponse.json(guests); } catch (error) { console.error('Error fetching guests:', error); return NextResponse.error(); } } export async function PUT(request: NextRequest) { try { const { name, email, comment } = await request.json(); const newGuest = await prisma.guest.create({ data: { name, email, comment, }, }); console.log(newGuest); return NextResponse.json(newGuest); } catch (error) { console.error('Error creating guest:', error); return NextResponse.error(); } } ``` On the client side I calls it in the way below: ``` const submitData = async (e: React.SyntheticEvent) => { e.preventDefault(); try { const response = await fetch('/api/guest', { method: 'PUT', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ name, email, comment }), }); if (response.ok) { const newGuest = await response.json(); setGuests((prevGuests) => [...prevGuests, newGuest]); setSuccessMessage('Signed successfully, thank you! ===>' + response); setErrorMessage(''); router.refresh(); } else { throw new Error('Failed to submit data'); } console.log(response); } catch (error) { setErrorMessage('Error submitting data. Please, try again. ===>' + error); setSuccessMessage(''); console.error('Error:', error); } }; ``` It's a simpliest app to store and print data, without any client authentication. I can fetch data with GET method without any issues, but the PUT method has been returning `500 Internal` error. Can you give me any idea for what is missing? Thank you. Pauline P. Narvas (@pawlean) · 2024-08-27 Hi, @ivanzanoth-gmailcom! I can see in your title [SOLVED], is this all sorted now? :smile: ivan (@ivanzanoth-gmailcom) · 2024-08-27 · ♥ 1 Helo @pawlean , yes, it was a trivial neglect in reading the logs. Namely: <code>Unique constraint failed on the fields: (`email`)</code> Thanks. Pauline P. Narvas (@pawlean) · 2024-08-27 · ♥ 1 It happens sometimes. :smile: Thanks for coming back with your solution!
