That is just a warning letting you know that the library, while it tries to
automatically mask bad values using metadata like the "valid_range" attribute,
is ignoring the "valid_range" attribute for your variable because the attribute
has a different type than that of the original data values. It's only a
warning, so your data should be fine, it's just that bad/missing values may not
be properly masked.
For more information, see this GitHub issue:
