Hi @jeanschneider,

can you provide code for your app, preferably on snack? I'm afraid I can't help you without that.

[jeanschneider]

Hello,
Thanks for your response.
I tried importing the code to snack but infortunately it doesn't work (there are so many other errors probably happenning before this one).
Anyway here is the code :

I saw there is an issue for the same problem opened on the react github and on stackoverflow. It seems like it suddenly happened (no changes have been made to the code, just opened it a few days later and it wasn't working anymore). On stackoverflow, the guy solved it by downgrading to 1.4.0. It didn't solved the issue for me

Oh, this is a huge repro 😄
I can't really debug on this one, please try submitting some smaller repro.
I think this may be related to react-navigation which uses reanimated in such a way that triggers this error

You can try checking if NodesManager.java in reanimated java sources from node_modules contains else if ("param".equals(type). In your app, it throws an exception on line 277. This error is strange because on line 270 we check for param type, so it shouldn't be happening

Yeah, it's a decent sized project !

Okayyy so latest updates ! I realized the downgrade did not work (bcz of expo cache, so dumb I did not think about this one 🤬). Now that I downgraded reanimated to 1.4.0, it starts again !

[jakub-gonet]

Alright, I'll close this one for now in that case, because it's probably related to proc changes in 1.4 and we're aware of this problem. If you provide smaller repro I'm happy to reopen

steps for windows machine:

1. Delete .expo and node_modules folder
2. run command npm install [email protected]
3. run command for clear expo cache, expo r -c
