Panic on a table that only has an ID, "called Option::unwrap() on a None value"

[divyenduz]

This can be seen on this table in mysql/sportsdb database

CREATE TABLE `baseball_defensive_group` (
  `id` int(11) NOT NULL auto_increment,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

To reproduce, import the SQL of this table locally into a MySQL database and introspect it (prisma2 introspect --url <db-connection-string>). Then run the following client call:

const { PrismaClient } = require('@prisma/client')

const prisma = new PrismaClient()

async function main() {
  const data = await prisma.baseball_defensive_group.create()
  console.log(data)
}

main()

It yields the error:

This is a non-recoverable error which probably happens when the Prisma Query Engine has a panic.
Please create an issue in https://github.com/prisma/prisma-client-js describing the last Prisma Client query you called.

+1 on this issue. only getting in when running prisma in docker.

[janpio]

Can you please create a new issue @jaywalklabs and elaborate on this? We are getting this here in all contexts, so it would be interesting to see what is different about your situation. If you can include the relevant part of your code and schema.

[dpetrick]

A fix will be available from dev 2.1.0-dev.18 onwards.
