prisma: Prisma2 not working with netlify-lambda

I am using the netlify lambda cli. Not the netlify cli. https://github.com/netlify/netlify-lambda

Following up from the discussion here: https://github.com/prisma/prisma2/issues/952

When I try to run prisma2 generate I get this error

Error: The `platforms` field on the generator definition is deprecated. Please rename it to `binaryTargets`.

When I switch platforms to binaryTargets it runs generate fine. But I still get this error on invocation

Request from ::1: GET /.netlify/functions/hello
Response with status 500 in 528 ms.
Error during invocation:  Error: Error in Photon: 
Error: Photon binary for current platform darwin could not be found.
Photon looked in null but couldn't find it.
Make sure to adjust the generator configuration in the schema.prisma file:
generator photon {
  provider      = "photonjs"
  binaryTargets = ["native", "rhel-openssl-1.0.x", "darwin"]
}
Please run prisma2 generate for your changes to take effect.
Note, that by providing `native`, Photon automatically resolves `darwin`.

Here is my generator section of my schema.prisma

generator photon {
  provider = "photonjs"
  binaryTargets = ["native", "rhel-openssl-1.0.x"]
}

Even if I try adding darwin to that list it still errors, and just adds another darwin to the error message.

Make sure to adjust the generator configuration in the schema.prisma file:

generator photon {
  provider      = "photonjs"
  binaryTargets = ["native", "rhel-openssl-1.0.x", "darwin", "darwin"]
}
