[Introspection] Crashes when default value contains line breaks

I’ve observed the Prisma 2 introspection code crash when a default value is not a constant, but some expression, in my case also containing a new line.

Consider a column in postgres with the following default value:

'Concatenated'||E'\n';

Introspection crashes with:

Schema parsing

error: Unexpected token. Expected one of: 
  -->  schema.prisma:389
   | 
388 |   columnName    String               @default("(Concatenated || 
389 | )")
   | ^ Unexpected token.

lol no - just a comment that the default value is missing here because %explanation+link%

Suggestion:

/// The default value of this field was skipped as it is currently not supported by Prisma. 
/// This does not negatively influence your app, as the default is enforced by the database.

Just don’t spend any time trying to print a multi-line, commented-out default value. No mess like this:

model User {
  name String //@default("who thi
//nks a name should
//
//have line breaks????!?")
}
