Source map issue in generated client (5.13.0)

[mastersilv3r]

Bug description

This used to work perfectly till Prisma 5.11.0
When I generate client using prisma generate command, the generated client has now started giving this issue.

Source Map Issue (Compile time)

When building (transpiling) my project which has generated prisma client, the below mentioned error shows up.
Workaround
To stop this error from showing up - disable generation of source map in .swcrc or tsconfig.json

How to reproduce

Expected behavior

There should be no source mapping errors about relative URL like shown in the above error log.

Prisma information

datasource db {
  provider = "postgresql" // or "mysql", "sqlite", "sqlserver" etc.
  url      = env("POSTGRES_URL")
}

generator client {
  provider = "prisma-client-js"
  output   = "./prisma-clients/lending_service_db"
  previewFeatures = ["metrics"]
}

model User {
  id               Int               @id @default(autoincrement())
  pan_number            String            @unique ///@encrypted
  // password         String            ///@encrypted
  // name             String?
  loanApplications LoanApplication[]
}

model LoanApplication {
  id             Int             @id @default(autoincrement())
  createdAt      DateTime        @default(now())
  updatedAt      DateTime        @updatedAt
  status         String          // e.g. "pending", "approved", "rejected"
  amount         Float
  interest       Float
  duration       Int
  bank_name      String
  userId         Int             // Foreign key to associate with User
  // loanProductId  Int             // Foreign key to associate with LoanProduct
  user           User            @relation(fields: [userId], references: [id])
  // loanProduct    LoanProduct     @relation(fields: [loanProductId], references: [id])
}

I just noticed this in our CI today as well. I did not check yet if this happens with earlier versions of Prisma.

From what I see, it's not causing any problem, but that's an ugly error message. @mastersilv3r Is that what you obverse, too?

I suspect that this is related to swc-project/swc#8869 🤔
