The Function has some bad code in it Since it's minified it's hard to know what. I'd suggest running locally to find out wrangler pages dev <out dir>

tony•2y ago

that function is being generated from Building Nitro Server (preset: cloudflare_pages)

Walshy•2y ago

I'm aware I'm just telling you the issue

tony•2y ago

thank you. let me see if i can get that page the function is:

import { prisma } from '../prisma'

export default defineEventHandler(async(event) => {
    const users = await prisma.user.findMany()
    return users
})

import { prisma } from '../prisma'

export default defineEventHandler(async(event) => {
    const users = await prisma.user.findMany()
    return users
})

very basic

Walshy•2y ago

One of these things is undefined Again, hard to know with minification

tony•2y ago

using https://nitro.unjs.io/deploy/providers/cloudflare#cloudflare-pages would I be able to run the wrangler command locally and pass that preset? looking in https://developers.cloudflare.com/workers/wrangler/commands/#pages i do not see a preset option the directory would be .output/server

Walshy•2y ago

NODE_PRESET=cloudflare-pages nitro build or something and then just wrangler pages dev <output>

tony•2y ago

ty So I have added a data proxy and updated the build script

tony•2y ago

and now the error is:

adlab.a8a32591-95a1-...

tony•2y ago

I have the DATABASE_URL in the pages environment variables

Isaac McFadyen•2y ago

Have you generated the Prisma project as described in the Prisma guide? https://www.prisma.io/docs/data-platform/data-proxy/use-data-proxy#generate-prisma-client-for-the-data-proxy

make sure that Prisma Client is auto-generated with the --data-proxy flag as described below.

tony•2y ago

yes,

import { PrismaClient } from '@prisma/client/edge'

export const prisma = new PrismaClient({
    errorFormat: 'minimal'
})

export default defineEventHandler(async() => {
    return prisma.user.findMany().catch((error) => {
        console.log(error)
    })
})

import { PrismaClient } from '@prisma/client/edge'

export const prisma = new PrismaClient({
    errorFormat: 'minimal'
})

export default defineEventHandler(async() => {
    return prisma.user.findMany().catch((error) => {
        console.log(error)
    })
})

I have also deployed it as a worker, and although it compiles it takes a very long time to get a response https://users-worker.data-well.workers.dev/

I had the same experience (am using Nuxt 3). Tried to connect to Supabase DB (Postgres). Now already tried DataProxy but the error is still the same. Hopefully somebody here can help. Just found the fix. I changed the code to: import { PrismaClient } from "@prisma/client/edge"; and now it is working!
