terraform is initialized in an empty directory - gitlab

Question

I am trying to get terraform to perform terraform init in a specific root directory, but somehow the pipeline doesn't recognize it. Might there be something wrong with the structure of my gitlab-ci.yml file? I have tried moving everything to the root directory, which works fine, but I'd like to have a bit of a folder structure in the repository, in order to make it more readable for future developers.
default:
tags:
- aws
image:
name: hashicorp/terraform:light
entrypoint:
- '/usr/bin/env'
- 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
variables:
# If not using GitLab's HTTP backend, remove this line and specify TF_HTTP_* variables
TF_STATE_NAME: default
TF_CACHE_KEY: default
# If your terraform files are in a subdirectory, set TF_ROOT accordingly
TF_ROOT: ./src/envs/infrastruktur
before_script:
- rm -rf .terraform
- terraform --version
- export AWS_ACCESS_KEY_ID
- export AWS_ROLE_ARN
- export AWS_DEFAULT_REGION
- export AWS_ROLE_ARN
stages:
- init
- validate
- plan
- pre-apply
init:
stage: init
script:
- terraform init
Everything is fine until the validate stage, but as soon as the pipeline comes to the plan stage, it says that it cannot find any config files.
validate:
stage: validate
script:
- terraform validate
plan:
stage: plan
script:
- terraform plan -out "planfile"
dependencies:
- validate
artifacts:
paths:
- planfile
apply:
stage: pre-apply
script:
- terraform pre-apply -input=false "planfile"
dependencies:
- plan

You need to cd in your configration folder in every job and after each job you need to pass the content of /src/envs/infrastruktur where terraform is operating on to the next job via artifacts. I omitted the remainder of your pipeline for brevity.
before_script:
- rm -rf .terraform
- terraform --version
- cd $TF_ROOT
- export AWS_ACCESS_KEY_ID
- export AWS_ROLE_ARN
- export AWS_DEFAULT_REGION
- export AWS_ROLE_ARN
stages:
- init
- validate
- plan
- pre-apply
init:
stage: init
script:
- terraform init
artifacts:
paths:
- $TF_ROOT
validate:
stage: validate
script:
- terraform validate
artifacts:
paths:
- $TF_ROOT
plan:
stage: plan
script:
- terraform plan -out "planfile"
dependencies:
- validate
artifacts:
paths:
- planfile
- $TF_ROOT
