httpServer sample app not linking to lighttpd

I am having an issue when trying to run the httpServer sample app.
The issue seems to be with this line in the adef file.

`/legato/systems/current/apps/httpServer/read-only/bin/lighttpd /app/bin/lighttpd`

I am getting the following error in logread when starting the app:

Failed to create link at '/app/bin/lighttpd'

I am running it on a MangOH Yellow with wp7xx release 12 and Legato version 20.04.0. Any ideas on how to fix this issue?

Is it same issue as this one?

It may be, but I tried the suggestions there with no luck.

how did you modify???

I changed the dir section to the below:

dir:
{
/proc / // needed by app script, and for listing running processes
/bin /usr/bin
/sbin /
/legato/systems/current/bin /legato/systems/current/
/legato/systems/current/lib /legato/systems/current/
/legato/systems/current/apps /legato/systems/current/
}

How about change to the following?
It is working fine on wp76 fw r13.

dir:
{
/proc / // needed by app script, and for listing running processes

/*
/bin /usr/bin
/sbin /
*/
/usr/lib /usr/
/usr/bin /usr/
/usr/include /usr/

/legato/systems/current/bin /legato/systems/current/
/legato/systems/current/lib /legato/systems/current/
/legato/systems/current/apps /legato/systems/current/
}
