Export Image Error in Google Earth Engine Python API – Solutions

google-earth-engine

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)
  File "C:\OSGEO4~1\apps\Python37\lib\site-packages\ee\data.py", line 1126, in exportImage
    return startProcessing(request_id, params)
  File "C:\OSGEO4~1\apps\Python37\lib\site-packages\ee\deprecation.py", line 32, in Wrapper
    return func(*args, **kwargs)
  File "C:\OSGEO4~1\apps\Python37\lib\site-packages\ee\data.py", line 1100, in startProcessing
    return send_('/processingrequest', args)
  File "C:\OSGEO4~1\apps\Python37\lib\site-packages\ee\data.py", line 1669, in send_
    raise ee_exception.EEException(json_content['error']['message'])
ee.ee_exception.EEException: Invalid request: 'driveFolder': Must be at most 255 characters.

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?

I haven't test it, but I think the issue comes from parsing task_config as a dictionary. To keep your code without much modifications, just do:

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

the ** will unpack the dict parsing it as keywords.
