FileSystem copyAsync not working in iOS and Expo 50

Question

I have the following code with a React Native in iOS, using Expo 50.

const uri = photo.uri; // an example of this value is ph://ED7AC36B-A150-4C38-BB8C-B6D696F4F2ED

const uriParts = uri.split(".");
const fileType = uriParts[uriParts.length - 1];
const time = new Date().getTime();

const newUri = `${FileSystem.documentDirectory}/${time}.${fileType}`

await FileSystem.copyAsync({
   from: uri,
   to: newUri,
});

I'm getting the following error:

Error: Calling the 'copyAsync' function has failed
→ Caused by: File '' is not readable
