Do you know what version of texinfo.tex is being used?  When you run 
TeX, a message should be printed like:

Loading texinfo [version 2017-07-04.16]: pdf, fonts, markup, glyphs,

which shows which version it is.

If you have an older version, you can get the newest version from

I tried using @deftypefn as in your example:

but didn't get any errors.

\input texinfo


@node One
@chapter One

@deftypefn category type function(@var{input})
Does something on @var{input}
@end deftypefn

@node Two
@chapter Two

@printindex fn



\entry{function(input)}{1}{\code {function(\var {input})}}

What has happened here is that file.toc has file handle 0 when it is 
open in TeX.  \fnindfile as mentioned in the error message should have
the file handle number of file.fn, another output file, and the \entry
lines should be written to that file instead, not file.toc.  That is 
why the table of contents is a mess.
