Slicing KeyError #226

Closed J6767 closed 8 months ago

J6767 commented 10 months ago

I have adapted the basic example for L1C Sentinel-2 and in most cases it is running fine. However, I have encountered some rare cases where the following fails:

aoi = b11_b12_rgb.loc[..., y_utm + m_buffer:y_utm - m_buffer, x_utm - m_buffer:x_utm + m_buffer]

raise KeyError(
KeyError: "cannot represent labeled-based slice indexer for coordinate 'time' with a slice over integer positions; the index is unsorted or non-unique"

Printing the time values, they look unique and sorted, but one product has a NaT, is that causing the error?:

 '2021-11-17T18:04:02.427000000' '2021-11-25T18:13:53.443000000'

 '2021-12-17T18:04:02.455000000'                           'NaT']

If so, how can I remove that product? Many thanks!

can you provide a reproducable example ? We'd have to see why does that stac item doesn't provide a timestamp, could be a faulty object from the stac

Without a reproducible example, there's not much we can help with here, so I'm going to close this. @J6767, if you'd like to provide a reproducer, feel free to re-open.
