Using config file produces misleading comment with module paths from clone of main branch and the real module paths about infracost HOT 6 OPEN

Additionally I just tested this setup for a multi terraform project repo, and the result is similar to when using only one project - the reports are shown for base modules for main branch and for real modules.

So in conclusion, am I doing something wrong?

@Tomasz-Kluczkowski what is your CONFIG_FILE variable set to? Also does it work if you copy the config file into /tmp/base before running infracost breakdown, e.g.:

    - |
      cp infracost.yml /tmp/base
      cd /tmp/base
      infracost breakdown --config-file=${CONFIG_FILE} \
                          --format=json \
                          --out-file=infracost-base.json

Hi,
I am running in gitlab. In my repo the .infracost.yml is in the root of the project.

CONFIG_FILE: ${CI_PROJECT_DIR}/.infracost.yml

from infracost.

I will try running with your instructions and report back.

ok I changed the code to be:

      cp .infracost.yml /tmp/base
      cd /tmp/base
      infracost breakdown --config-file=.infracost.yml \
                          --format=json \
                          --out-file=infracost-base.json

    - |
      cd -
      infracost diff --config-file=.infracost.yml \
                     --compare-to=/tmp/base/infracost-base.json \
                     --format=json \
                     --out-file=infracost.json

Which produced expected results for no changes to resources:

Infracost report

💰 Monthly cost will not change

_{This comment will be updated when code changes.}

And also when resources were changed:

💰 Monthly cost will increase by £9 📈

So I think your solution is correct @aliscott . Should then infracost's documentation here: https://gitlab.com/infracost/infracost-gitlab-ci/-/tree/master/examples/multi-project-config-file be updated?
