Bytes type is not translated into Buffer type - Type/Import Error

[austenstrine]

Bug description

When adding a Bytes field into a schema.prisma table, the resulting generated class sets the property as type Bytes, which is not a typescript type. This throws a type error. It should be Buffer instead.

How to reproduce

Add a Bytes type into the schema.prisma

Run npx prisma generate

Expected behavior

I expected the generator to convert Bytes into the Buffer type.

Prisma information

generator client { provider = "prisma-client-js" engineType = "binary" binaryTargets = ["native", "linux-musl-arm64-openssl-3.0.x"] previewFeatures = ["fullTextSearch"] }

datasource db { provider = "postgresql" url = env("DATABASE_URL") }

generator class_validator { provider = "prisma-class-validator-generator" }

model FileUpload { id Int @unique @id @default(autoincrement()) businessId Int userId Int? email String? schema Json? lineItemCount Int pdfName String? pdfData Bytes? @db.ByteA pdfUri String? spreadsheetName String? spreadsheetData Bytes? @db.ByteA spreadsheetUri String? approved Boolean @default(false) errors String[] attempts Int @default(0) created DateTime @default(now()) updated DateTime @updatedAt }

This PR fixes the issue: https://github.com/omar-dulaimi/prisma-class-validator-generator/pull/15

[austenstrine]

Until such a time as this package approves the PR that adds support for Bytes (as Buffer), feel free to link this "build" branch directly in your projects. It's literally just a compiled version of the PR:

With yarn: yarn remove prisma-class-validator-generator yarn add prisma-class-validator-generator@https://github.com/austenstrine/prisma-class-validator-generator.git#build

With npm: npm uninstall prisma-class-validator-generator npm install austenstrine/prisma-class-validator-generator.git#build

Obviously not as good as the PR just getting merged, but better than waiting if you're in a pinch and need a solution "now" like I do.
