Packer fails on Gitlab-CI with {message:401 Unauthorized}: command not found - docker

Question

I am trying to use packer with GCP in gitlab-ci but every time I get to the packer build it will fail with the following error:
starting remote command: chmod +x /tmp/script_5147.sh; DEBIAN_FRONTEND='noninteractive' PACKER_BUILDER_TYPE='googlecompute' PACKER_BUILD_NAME='my_vm' /tmp/script_5147.sh
==> googlecompute.my_vm: /tmp/script_5147.sh: line 1: {message:401 Unauthorized}: command not found

apt update
apt install -y curl
curl -fsSL https://deb.nodesource.com/setup_18.x | bash -
apt upgrade -y iptables
# The iptables-persistent must be installed in order to create the /etc/iptables/rules.v4 file
apt install -y nginx libzmq3-dev nodejs ipset iptables-persistent net-tools libre2-dev
npm install -g yarn
rm /etc/nginx/sites-enabled/default
The packer is working locally (also with the image) and I created a VM in GCP all of them are working, only in gitlab it fails.
I created a custom image of packer and it still failed for me on gitlab.
I will try to move it to my own runner but it will take a few days for me.
Would love if someone could help me figure it out.

Ok, I figured out the problem.
I curled some files and the token was not good so when it got to packer it failed because the files were not as expected.
I printing the 401 of the curl.
