Path must be a string. Received undefined

So I want to rebuild my app on the server on every git push. When running a simple script which is just executing cd /.../ && tsd install it works fine. But in my script it's just failing and I have no idea why after some time troubleshooting it. I would be glad If you could look over it.
My server side script (yeah I know it's a bit rough, running as root to restart a service, but it's just a development prototype) looks like this

#! /bin/bash
hash=$1
dst=/var/www/xxx/builds
app=/var/www/xxx/app
log=/var/www/pushhook/logs/"$hash".log
npm=/usr/bin/npm
tsd=/usr/bin/tsd
bower=/usr/bin/bower
gulp=/usr/bin/gulp

/usr/bin/git clone --depth 1 git@zzz/xxx.git $hash &>>$log
mv $hash $dst/

cd $dst/$hash
cd src
$npm install &>>$log

cd backend
$tsd install &>>$log
$npm install &>>$log
cd ..

cd crawler
$npm install &>>$log
cd ..

cd frontend
$bower install --allow-root &>>$log
cd ..

$gulp build &>>$log

rm $app
ln -s $dst/$hash/src/bin/www.js $app
chown -R www:www /var/www/xxx/
chmod 700 $app
service xxx restart

Hi,

I have recently starting getting the same error when running tsd via gulp:
