Hi guys, I am new here and I tried to copy App.js from Basic example and put in my SortableMyList.js file to see how it works. There is big error in my console and i have no idiea what is it. I tried to Google it and search these type of error but couldn't find any.
Sorry I don't know where to ask, let me know if i need to ask this somewhere else.

Here is the screenshot of my code, browser running expo react native and error in console.

Here is my package.json dependencies

You could change Line 35 of sortableList.js to ... oneOfType(... instead of ... oneOf(... .
oneOf needs a value while oneOfType can take a general type like string or number. If oneOf gets a type without a value, like it does here, the value will be null.

Thanks for the suggestion, it worked. I hope the issue get fixed in the original code. Do you think this issue should be closed ? Also question, if i build my project with this manual fix, will it be a problem ?

[PeturSigurdsson]

If you fix it manually you should keep it outside of node_modules in a lib folder or something. Otherwise it could be a source of annoyance, since package managers will update it periodically and undo your manual fix.
Edit: I am not doing it in this case because the error doesn't break the component.

i got the same error after upgrading react-native from .59 -> .62

@anil3a an alternative solution to what @PeturSigurdsson suggested would be using patch-package to create a patch that is applied to the library inside the node_modules each time you run npm install/yarn

It would be advisable to lock the react-native-sortable-list version in the package.json file as long as you are using the patch since it corresponds to the library version
