Ionic window.resolveLocalFileSystemURL not working for jpgs

I'm using the gallery to access images to upload. I'm having no trouble when I am uploading the image uri directly, but when I need to use fileEntry (for multi-part uploads) jpgs are not returning a fileEntry from their uri. Note: i'm using async:await, but I have the same issue with standard promises

For example the following is the code I'm using to get the image uri

var imageUri = await this.takePicture(Object.assign(this.defaultOptions,{sourceType:this.camera.PictureSourceType.SAVEDPHOTOALBUM}));
let newFile = new File([imageUri], "filename");
this.uploadFile(newFile);

The following is the code for takePicture() that returns the imageUri

try{
  return await this.camera.getPicture(options);
}catch(err){
  ...handle error
}

This code above successfully uploads both png and jpg files.

This code below fails to retrieve a fileEntry for only jpg files.

    /**
   * Returns a file entry for the image uri provided
   * @param imgUri image Uri to get file entry for
   */
  private async getFileFromImageUri(imgUri){ 
    try{
      var fileEntry = await this.resolveFileAsPromise(imgUri);
    }catch(err){
      // fileEntry = await this.createNewFileEntry(imgUri);
      this.presentToast('Error while selecting image.');  //TODO: images that are .jpg seem to have trouble being resolved to a file.
    }
    return fileEntry;      
  }

resolveFileAsPromise(ImgUri); is a promise wrapper for window.resolveLocalFileSystemURL(imgUri, resolve, reject); It returns the following error

FileError {code: 5} for jpgs only. The error code means that there was some trouble with the format of the jpg? This doesn't make sense to me as all of that is being handled internally. The images are not corrupted or anything so it leads me to believe that possibly the error code is misleading? error code docs

Has anyone encountered this issue? I am testing on a live android device (not an emulator).

I feel that the above demonstrates that the image uri is not the problem since it works to upload images when I don't need to get to the fileEntry. But, when I do, it works for only a particular filetype pngs.
