Issue with Ionic 3 types while using the copyTo function on fileEntry

While working on my Ionic 3 app, I encountered an issue when trying to copy a file to a new directory using the Cordova plugin file. The error message states:

Argument of type 'Entry' is not assignable to parameter of type 'DirectoryEntry'. Property 'createReader' is missing in type 'Entry'

Has anyone found a solution to overcome this problem?

Here's the code snippet causing the issue:

this.file.resolveLocalFilesystemUrl(sourceFilePath).then(fileEntry =>
{
  if(newName == null)
    newName = fileEntry.nativeURL.split('/').pop();
  else if(newName == "")
    newName = fileEntry.nativeURL.split('/').pop();

  this.file.resolveLocalFilesystemUrl(targetDirectoryPath).then(dirEntry => {
    fileEntry.copyTo(dirEntry, newName, entry =>{
      resolve(newName);
    }, function(error){
      resolve(newName);
    });
  });
});

Answer №1

After reviewing the information in the reference manual, it appears that substituting the second instance of resolveLocalFilesystemUrl with resolveDirectoryUrl is necessary to obtain a valid DirectoryEntry for use in the copyTo function.
