introspect fails on SQLite

[janpio]

prisma/schema.prisma:

datasource db {
  provider = "sqlite"
  url      = "sqlite:./../1093.db"
}

generator client {
  provider = "prisma-client-js"
}

Zipped 1093.db file to put in root of project:
1093.zip
(originally via #1093 (comment))

When I run prisma2 introspect I get this:

I can reproduce Error [ERR_STREAM_DESTROYED]: Cannot call write after a stream was destroyed

It looks like the error is from the introspection engine, here is the SQL for this database from sqlite3 prisma/1093.db .dump > 1093.sql

When I create a new sqlite database from this .sql I get the same error.

PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE IF NOT EXISTS "Group"
(
	id integer not null
		primary key autoincrement,
	name varchar(255)
);
CREATE TABLE User
(
	id integer not null
		primary key autoincrement,
	email varchar(255) not null,
	password varchar(255) not null,
	created_at datetime,
	updated_at datetime
);
CREATE TABLE GroupToUser
(
	user_id integer
		references User,
	group_id integer
		references "Group"
);
DELETE FROM sqlite_sequence;
COMMIT;

[janpio]

I think "Error [ERR_STREAM_DESTROYED]: Cannot call write after a stream was destroyed" is a follow up error when the Engine crashes. We might want to handle that better - you have a nice reproduction here ;)

The output changed on alpha 927, I see "libs/sql-schema-describer/src/sqlite.rs:309:37" that wasn't there before.

I haven't managed to get a readable error from the JS cli, but running the introspection engine directly, I get Error: Some(Object({"is_panic": Bool(false), "message": String("The introspected database was empty: sqlite:./../1093.db"), "meta": Object({"connection_string": String("sqlite:./../1093.db")}), "error_code": String("P4001")})) (with the database from the .zip Jan posted in the description), so it looks like this should be reported as a known error?

[janpio]

Hm, database is definitely not empty:

(Via download and unzip of the link above)

This was caused by a shortcut in the Sqlite foreign key definition btw.

They allow you to write:
userid Int References user instead of userid Int References user(id)

Unfortunately the meta information calls then don't automatically provide the Information about the referenced column which caused the crash. This is now being handled.

Awesome @do4gr 🚀
