Only one file name allow when changing current working directory automatically

When changing current working directory automatically with the command in vimrc:
au BufEnter * if &ft != 'help' | ProjectRootCD | endif

Get the error:
Error detected while processing BufEnter Auto commands for "*":
E172: Only one file name allowed: ProjectRootCD | endif

Confirmed. From reading the documentation, it's not possible to use | inside autocommands.

The easiest solution would be to change it to:

autocmd BufEnter * ProjectRootCD

I think I'll change the documentation to that, and perhaps move the 'help' logic into ProjectRootCD itself.

Okay, never mind my last comment. The way this can be done is:

au BufEnter * if &ft != 'help' | call ProjectRootCD() | endif

Which is wrong in the builtin documentation. I'll update it. Thanks for reporting!
