I am trying to use the GEE Python API to export an image to Google Drive.
Everything works smooth, except the exporting stage.

```
boundary = ee.Feature(Countries.first()).geometry().bounds().getInfo()['coordinates']

task_config = {
    'fileNamePrefix': 'image',
    'crs': 'EPSG:4326',
    'scale': 500,
    'maxPixels': 10e15,
    'fileFormat': 'GeoTIFF',
    'skipEmptyTiles': True,
    'region': boundary ,
    'folder': 'myfolder'
    }

task = ee.batch.Export.image.toDrive(image, str('image'), task_config)
task.start()

```

Where I get the following error: 

```
Traceback (most recent call last):
  File "<input>", line 19, in <module>
  File "C:\OSGEO4~1\apps\Python37\lib\site-packages\ee\batch.py", line 81, in start
    result = data.exportImage(self._request_id, self.config)

```

It's like the parameter 'folder' was not read correctly, because in my Google Drive I then find an emtpy (since the task fails) folder named not after 'myfolder', as I specified, but after the long, entire list of parameters I specified in task\_config. Any clue?
