Here is the detailed error:

and here is the line with the issue:

[AuroreAA]

everything is working well with flextable_0.9.1

[aalfons]

From the NEWS file of package flextable for version 0.8.3:

• functions add_header_row(), add_footer_row(), add_body_row(), add_header_lines() and add_footer_lines() now supports formatted paragraph made with as_paragraph()

I guess that versions <= 0.8.2 require a character string and don't support paragraphs that have formatting in add_footer_lines().

We just need to add the requirement for flextable (>= 0.8.3) in the DESCRIPTION file.
