[Bug?]: yarn rw console hangs for 10 seconds when typing 'db'

[kalaracey]

What's not working?

I am going through the tutorial and I have gotten to the part where you begin to use yarn rw console. However, when I type db. (i.e. the beginning of db.post.findMany(...)) the console hangs for five to ten seconds at db. If I backspace from e.g. db.post to the 'd' character, it will similarly hang at db before backspacing through 'b' for five to ten seconds.

Perhaps there is some sort of autocomplete that is blocking the thread.

How do we reproduce the bug?

git clone https://github.com/redwoodjs/redwood-tutorial
cd redwood-tutorial
yarn install
yarn rw prisma migrate dev
yarn rw g secret

Then set up the SESSION_SECRET in .env.

Finally, open yarn rw console and attempt to type db.post.findMany().

What's your environment? (If it applies)

Hey @kalaracey thanks for opening the issue! I can reproduce this behaviour on our test project so it's definitely happening.

Looking at the git history it looks like this command hasn't had much attention for a long time. I wasn't on the team when this was created so don't have any specific insight to offer at the moment. I can do my best to try and help you out if there's anything specific you come across.

A little notice since you said you'd be interested in working on this - which is awesome btw! The team is trying to focus on a few important milestones for our next epoch so we might not be able to be as responsive to this issue as we would like to be. I'll still try to make sure we get back to you though!

I've been running into this. Sharing some debug info I found today - if you paste something that goes past the "db", the console doesn't hang, e.g. db.. Seems like it's an issue with how the repl is interpreting the prisma client accessed through db.

[cyberious]

Additionally, when you open a console, as long as you do not start with db it does not freeze. It seems like some eager fetching off all possible Prisma objects in the DB or waiting on a promise that may never come.

Additionally, even using await in front of db the query works with absolutely zero hang.

I am also seeing this, however it doesn't seem to resolve itself even after waiting 10 seconds. Pasting directly into the terminal works and prefixing with await also works.

The console isn't getting much use, so we likely won't get to investigating this anytime soon. But please keep commenting and/or reacting to posts to indicate interest in this issue to keep it on our radar ✈️

[ymc9]

It should be caused by this one: prisma/prisma#18292

Mind if I make a PR @Tobbe ?
