Prisma does not work with Cloudflare Workers (for me)

Bug description

I wanted to use Prisma with Cloudflare Workers so I followed the official guide in docs. Didn’t work (problems with env). Eventually I was able to resolve the issue after reading through issues here. But now Prisma shows ones of these errors:

1. PrismaClient is unable to be run in the browser.
2. Datasource URL must use prisma:// protocol when --data-proxy is used

How to reproduce

1. Clone this reproduction repo
2. Run yarn install

For normal (non-edge) version:

1. Run yarn generate:normal
2. Run yarn dev:normal
3. Go to localhost:8787

For edge version:

1. Run yarn generate:edge
2. Run yarn dev:edge
3. Go to localhost:8787

Expected behavior

1. Should work locally without routing everything through the Data Proxy
2. Should not see Cloudflare Workers as browser

Prisma information

Could be found inside the repo.

Environment & setup

• OS: MacOS 12.6
• Database: PostgreSQL
• Node.js version: 18.7.0

Prisma Version

We understand.

I’ll close this issue now, but please report back again if this does not (technically) work for you as I described. You can also leave a +1 on that feature request I linked to, or even share your use case (how you would want to set up your testing locally with wrangler vs. live).

Ok so it’s exactly as I’ve feared. Well that sucks. Will try tomorrow and see how inconvenient it is. If it’s too inconvenient I’ll be forced in using a different setup not including Prisma which I don’t wanna do because I really like Prisma. But I need to start working on the project and can’t wait months for a better solution to be developed.
