TypeError: Setting a MultiIndex dtype to anything other than object is not supported

My columns are a multi-index. That seems to break df2gspread?

    123     cell_list = wks.range('%s%s:%s%s' % (first_col, start_row, last_col, start_row))
    124     for idx, cell in enumerate(cell_list):
--> 125         cell.value = df.columns.astype(str)[idx]
    126     wks.update_cells(cell_list)
    128 # Addition of row names
