seriesByRegion issue with some GEE datasets

[aboomer07]

I am using the code from one of the example notebooks to get a time series by region with a feature collection, and I am getting an error when using some different datasets.

The original code which works fine is:

test_site = ee.Geometry.Point([-71, -42]) test_feat = ee.Feature(test_site, {'name': 'test feature', 'buffer':0}) test_featcol = ee.FeatureCollection([ test_feat, test_feat.buffer(100).set('name', 'buffer 100', 'buffer', 100), test_feat.buffer(1000).set('name', 'buffer 1000', 'buffer', 1000) ]) col = ee.ImageCollection('COPERNICUS/S2').filterBounds(test_site) time_series = col.filterDate('2020-01-01', '2020-02-01')

chart_ts_region = ui.chart.Image.seriesByRegion(**{ 'imageCollection': time_series, 'reducer': ee.Reducer.median(), 'regions': test_featcol, 'scale': 10, 'band': 'B11', 'seriesProperty': 'name' })

Some other datasets work as well, such as the population count dataset. However, if I use the COPERNICUS/S5P/NRTI/L3_NO2 dataset, I get an error:

test_site = ee.Geometry.Point([-71, -42]) test_feat = ee.Feature(test_site, {'name': 'test feature', 'buffer':0}) test_featcol = ee.FeatureCollection([ test_feat, test_feat.buffer(100).set('name', 'buffer 100', 'buffer', 100), test_feat.buffer(1000).set('name', 'buffer 1000', 'buffer', 1000) ]) col = ee.ImageCollection('COPERNICUS/S5P/NRTI/L3_NO2').filterBounds(test_site) time_series = col.filterDate('2020-01-01', '2020-02-01')

chart_ts_region = ui.chart.Image.seriesByRegion(**{ 'imageCollection': time_series, 'reducer': ee.Reducer.median(), 'regions': test_featcol, 'scale': 10, 'band': 'NO2_column_number_density', 'seriesProperty': 'name' })

Yields this traceback:
