.transaction([]) fails with Request Timeout Error

Bug description

Using the new .transaction([]), I am seeing this on the client (JavaScript):

{ Error: Request Timeout Error
    at PrismaClientFetcher._request (/app/node_modules/@prisma/client/runtime/index.js:1:213208) code: 'UND_ERR_REQUEST_TIMEOUT', meta: undefined }

How to reproduce

Add multiple child records to an existing parent record.

const requests = [];

// loop that creates around 30 different requests, each with perhaps 500 to 1000 and puts them in the array like this:

requests.push(prisma.{entity}.update({
where: { id: {id that exists}},
data: {
  {related entity name}: {
create: [
 { between 500 and 1000 individual entities },
]
},
})

await prisma.transaction(requests);

Expected behavior

Should complete without throwing the exception.
