Launchd fails to execute a perl command from a shell script

Question

Hello all,
i have a little script that runs rsync. I use perl to add a timestamp to each line of output. Basically it goes like this:
#!/bin/bash
rsync -avz $sourceFolder $destinationFolder 2>&1 | perl -e "while(<>){s/^/$(date "+%Y-%m-%d %H:%M:%S") [rsync_backup.daily] /g; print;}"
Invoking this script from terminal works perfectly! Invoking it via launchd however fails. There is no error thrown, it just seems to not proceed.
Any help is appreciated.
Cheers.

This is the output from the shell:
