Trouble with modules not resolving when saving Snack via SDK

Expo Development Tools
1

Hey Expo team,

I’m utilizing the Snack SDK and trying to allow users to save their Snack session and be given a link to their project in Snack.

Here’s the URL of an example that I’m working with: My App - Snack. When I go to this project, click Run, and scan the QR code, I get the error:

File '(null)' isn't readable.
  Evaluating module://@draftbit/ui.js
  Evaluating module://App.js.js
  Loading module://App.js

It seems that the @draftbit/ui dependency isn’t being loaded. To fix this, I have to remove the @draftbit/ui dependency from package.json, re-add it, and shake + refresh my Snack session in the Expo mobile app. Things seem to work then. Not a huge deal in this case, but for some of our more complex projects with multiple dependencies it’s very hard to save using the Snack SDK and get a working Snack example.

Also, when I call the saveAsync method, the URL returned is https://expo.io/@snack/HkceKRDlH - I’m assuming this should be the URL posted above.

Hey Donald,
I suspect you aren’t adding the module to the session before saving.
Snack itself always uses the latest version of snack-sdk, so you can always see how we’re using it if something isn’t working for you. snack-web/App.tsx at master · expo/snack-web · GitHub

Cheers,
TC

Hey TC, that was exactly my issue. Thanks so much for the quick response. Appreciate the insight on snack-web as well, will use that as a reference going forward.
