wasp db studio failing to start after shutting it down

[fantapop]

I went through the installation process shown here

As I stepped through I was able to run wasp db studio and have it work. I briefly clicked around but there was no data there so it was uninteresting. I continued to follow the installation instructions. I started the app and created a user and a todo item. Then I went back to run wasp db studio again and its failing to start up.

I see this:

➜  app git:(main) wasp db studio

Looking in that checkpoint-nodejs directory, I see that there is indeed not a file or directory named .77865.0. I see these:

➜  app git:(main) ls /Users/chris/Library/Caches/checkpoint-nodejs/.

Do you have any thoughts on what I need to do to get that working again?

hey @fantapop. not sure what's going on here but since you've just started the app, try cancelling all the running processes and run wasp clean and then wasp start again. once everything is running correctly, try wasp db studio and let me know what happens :)

in the future, if this happens again, don't worry -- wasp db studio has failed on me at times. usually just restarting the dev server and trying it again fixes it

Weird I also never saw this. If this becomes consistent let us know again @fantapop .

[fantapop]

huh, yeah. It's working now. Thanks for the tip. I'll open a new issue if it keeps happening.
