Misleading "Can't reach database server" error when more than `32766` variables are bound inside an `IN` clause in Postgres

See original GitHub issue

Bug description

After upgrading to 2.29.1 my app is not starting properly anymore. I tested it with 2.29.0 --> same error, versions below (e.g. 2.28.0 and 2.27.0 are working fine).

I’m using Prisma in a NestJS application running in a Docker container with an Postgres DB running in a separate container.

I receive this error:

/app/node_modules/@prisma/client/runtime/index.js:35943
          throw new import_engine_core3.PrismaClientKnownRequestError(message, e.code, this.prisma._clientVersion, e.meta);
                ^

PrismaClientKnownRequestError3 [PrismaClientKnownRequestError]:
Invalid `prisma.XXX.findMany()` invocation:


  Can't reach database server at `db`:`5432`

Please make sure your database server is running at `db`:`5432`.
    at cb (/app/node_modules/@prisma/client/runtime/index.js:35943:17)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at async XXX.XXX (/app/dist/XXX/XXX.service.js:41:28) {
  code: 'P1001',
  clientVersion: '2.29.0',
  meta: { database_host: 'db', database_port: 5432 }
}

Before I receive this error message prisma migrate deploy runs successfully and two DB query are executed successfully. Therefore I highly doubt the error message, that the DB is not reachable. (Plus the error does not occur with the same DB and earlier versions of prisma.)

Executing the same app with DEBUG="*" (removed lines from express and NestJS for brevity):

Makes sense. The limit seems to be around 32767 parameters, https://github.com/prisma/prisma/issues/9275#issuecomment-920862822.

Setting QUERY_BATCH_SIZE seems to avoid the problem, however that’s rather a workaround than a solution:

The error message (“Cant’ reach database”) is wrong.
I couldn’t find documentation for QUERY_BATCH_SIZE.
I would expect prisma to handle these kind of limitations (and not letting the user run into this) - as it was prior to 2.29.0!

I ran into this issue as well, where I need to find lots of records (70000 +). Luckily for me a workaround exists where I’m querying with pagination like so (EDIT: it’s actually the preferred way to deal with any large amount of data):

const SOME_LIMIT = 200;

async function* findLotsOfRecords() {
  let i = -1;
  while (true) {
    const result = await prisma.record.findMany({
      where: { someCondition },
      skip: (i += 1) * SOME_LIMIT,
      take: SOME_LIMIT,
    });
    if (result.length === 0) break;
    yield result;
  }
}

// process queried records bit by bit if possible, it's better this way
for await (const res of findLotsOfRecords()) {
  // some logic with `res`
}

// if that's not possible you can always just collect it all
const arr = [];
for await (const res of findLotsOfRecords()) arr.push(...res);
// process `arr`
