Hello, I'm having trouble running the Sentinel S1 indices in the example 013-Time-Series-By-Region-Pandas.ipynb. It seems that the index parameters are not being passed. I don't know if it's a library update or some mistake on my part.

The code
point = ee.Geometry.Point([11.178576,51.122064]).buffer(100)

RAD = (ee.ImageCollection('COPERNICUS/S1_GRD')
.filterBounds(point)
.filterDate("2021")
.spectralIndices(index="QpRVI")
.select("QpRVI"))

ts = RAD.getTimeSeriesByRegion(geometry = point,
bands = ['QpRVI'],
reducer = [ee.Reducer.mean()],
scale = 10)

tsPandas = geemap.ee_to_pandas(ts)

Error:
Exception: Element.propertyNames: Parameter 'element' is required.

Thanks
