Unclear error when we guess a binary

[divyenduz]

To reproduce:

Deploy this project with Netlify's beta build (https://build-beta.netlify.com/). It should fail since we do not specify any binary targets and CI OS of Netlify is different from function runtime of Netlify.

So, the download happens in the build CI, which downloads the binary: query-engine-debian-openssl-1.0.x

At the runtime though, we need the binary for rhel-openssl-1.0.x.

That's where the maybe compatible kicks in and tries to run the available binary (only linux, hence this is hard to reproduce on a mac, windows machine).

The errors in the log is descriptive:

1:49:38 PM: 2020-02-10T12:49:38.605Z	b35ec6bb-f8be-4e38-9444-7c734e8e9d81	ERROR	warning Prisma Client could not resolve the needed binary for the current platform rhel-openssl-1.0.x.
Instead we found /var/task/src/node_modules/@prisma/client/runtime/query-engine-debian-openssl-1.0.x, which we're trying for now. In case Prisma Client runs, just ignore this message.

The error from the deployed function though, is not:

{"errorType":"Error","errorMessage":"\nInvalid `prisma.()` invocation in\n/var/task/src/functions/index.js:6:36\n\n\n\nEngine exited {\"target\":\"exit\",\"timestamp\":\"2020-02-10T12:49:38.642Z\",\"level\":\"error\",\"fields\":{\"message\":\"127\"}}","trace":["Error: ","Invalid `prisma.()` invocation in","/var/task/src/functions/index.js:6:36","","","","Engine exited {\"target\":\"exit\",\"timestamp\":\"2020-02-10T12:49:38.642Z\",\"level\":\"error\",\"fields\":{\"message\":\"127\"}}","    at PrismaClientFetcher.request (/var/task/src/node_modules/@prisma/client/index.js:82:23)"]}

Just surfacing the error from the logs should be enough.

To get rid of this error specifically in Netlify, we can use a generator configuration like this:

generator prisma_client {
  provider      = "prisma-client-js"
  binaryTargets = ["native", "rhel-openssl-1.0.x"]
}
