Vim9 - Can not get compile to recognize a deep variable

Hello,

I have read through the Vim9.txt, and can not find a solution to this issue.
When I call Parse(), the script version with the entire command on one line (|) gives error 'E121: Undefined variable: udp' in function add().
Both commands work if used on the command line, so its particular to running in a Vim9 script.

This works:
def g:Parse(): void
var udp: list<string>

:3global/^\s*<per/substitute/^\s*<per\(.\{-}"\)\{2}\|\s\+>.*$//g
:3substitute/\s\+.\{-}"\zs.\{-}\ze"/\=add(udp, submatch(0))/gn
# :3global/^\s*<per/substitute/^\s*<per\(.\{-}"\)\{2}\|\s\+>.*$//g
# | substitute/\s\+.\{-}"\zs.\{-}\ze"/\=add(udp, submatch(0))/gn

echo udp
enddef

This does not work:
def g:Parse(): void
var udp: list<string>

# :3global/^\s*<per/substitute/^\s*<per\(.\{-}"\)\{2}\|\s\+>.*$//g
# :3substitute/\s\+.\{-}"\zs.\{-}\ze"/\=add(udp, submatch(0))/gn
:3global/^\s*<per/substitute/^\s*<per\(.\{-}"\)\{2}\|\s\+>.*$//g
| substitute/\s\+.\{-}"\zs.\{-}\ze"/\=add(udp, submatch(0))/gn

echo udp
enddef

Thanks,
Chainsaw
