The code below represents my attempt at mosaicing sentinel bands. I get an error right at the end when trying to write the mosaics. It states:

TypeError: invalid driver: {'driver': 'GTiff', 'dtype': 'uint16', 'nodata': None, 'width': 20982, 'height': 20982, 'count': 1, 'crs': 'EPSG:32610', 'transform': Affine(20.0, 0.0, 499980.0, 0.0, -20.0, 6400020.0)}

with rasterio.open(output_b2, "w", **b2_out_meta) as dst:

You're passing a dict to rasterio.open as the driver argument. Either pass them all as named arguments or use **dict unpacking:

Instead of:

with rasterio.open(output_b2, "w", b2_out_meta) as dst:


with rasterio.open(output_b2, "w", **b2_out_meta) as dst:


with rasterio.open(output_b2, "w", driver='GTiff', dtype='uint16', etc...) as dst:
