Map.addLayer ERROR

[XingLong-Dai]

when run Map.addlayer(LandRemap), occur following error.Why?

Traceback (most recent call last):
File "C:\Users\Japycer\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\ee_plugin\extlibs_windows\ee\data.py", line 338, in _execute_cloud_call

Following is my code:

import ee
from ee_plugin import Map

roi = ee.Geometry.Polygon(
[[[101.17330962809865, 28.52538873146126],
[101.17330962809865, 19.34092009543521],
[117.56491119059865, 19.34092009543521],
[117.56491119059865, 28.52538873146126]]], {}, False)
dataset = ee.ImageCollection("COPERNICUS/Landcover/100m/Proba-V-C3/Global")
.filterDate('2019-01-01','2019-12-31')
.filterBounds(roi)
Land_Cover = dataset.mosaic().clip(roi).select('discrete_classification')

Land_Remap = Land_Cover.remap([0,20,30,40,50,60,70,80,90,100,111,112,113,114,115,121,122,123,124,125,126,200],
[4, 2, 2, 1, 3, 2, 2, 5, 5, 2, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5],
5,'discrete_classification')
Map.addLayer(Land_Remap)
Map.centerObject(roi)

Thanks !

That's because the second argument of ee.Geometry.Polygon is {}, but it should be None or 'EPSG:4326'

I'm trying to develop a QT C++ application that uses QGIS API, and I wonder if there is any way that I can use google earthengine plugin to load gee images. Thank u

EE plugin is written in python, I guess there should be a way to trigger python code that uses EE code and then pass results back somehow, I'd search for similar examples in QGIS forums/samples.

I get it, thank you very much !
