I am trying to annotate a MatrixTable with sample IDs written as integers, but I am encountering the key type mismatch error below. Is there a way to import the values into samples as strings to avoid this error? Should I use hl.import_lines? Thank you in advance.

    samples = hl.import_table(args.sub_annot, key='SAMPLE', impute=True)
