Greetings Infracost... I am getting the error (🧵 ) when running 
infracost diff --path=. --format=json --compare-to=infracost-base.json --out-file=infracost.json
where 
infracost-base.json
is from 
production/base
branch and 
infracost.json
is from the 
current
branch to be merged to 
production
branch.
Copy code
+ export 'INFRACOST_API_KEY=****'
+ infracost diff '--path=.' '--format=json' '--compare-to=infracost-base.json' '--out-file=infracost.json'

Hi @famous-eve-48967. In the 
infracost-base.json
are there any projects that have the same name?
f
I think let me share the 
groovy
code/stages for more context
Copy code
stage(name: "infracost-base.json - production") {
                        sh """

                    }

Hi @famous-eve-48967. In the 
infracost-base.json
are there any projects that have the same name?
@little-author-61621, it's the same project
l
Okay thanks, are you able to check the contents of the 
infracost-base.json
file? The issue might be because for some reason there’s identical projects in there.
f
Let me check it out

l
Ok, so the odd thing is the duplicate 
"name": "org/repo",
values in that file.
f
So how do I get red of it ??? since it's generated by the 
infracost breakdown ..
cmd ??
l
Do you use any *.tfvar files?
f
@little-author-61621 Yes
Copy code
tree | grep tfvar 
├── ter.auto.tfvars
├── terraform.tfvars
l
It’s hard to tell exactly what the issue is at the moment, but the best thing to do at the moment is create a 
infracost.yml
config file to specify the projects manually.
Copy code
version: 0.1
projects:
  - path: org/repo
    name: org-repo
    terraform_var_files:
      - ter.auto.tfvars
      - terraform.tfvars
And then run 
infracost
against that config file:
Copy code
infracost breakdown --config-file=infracost.yml --format json --out-file /tmp/infracost-base.json
...
infracost diff --config-file=infracost.yml  --format=json --compare-to=infracost-base.json --out-file=infracost.json
f
On it 🦾
l
I’m wonder if the underlying issue is related to https://github.com/infracost/infracost/issues/2624. So would be interested in knowing if this still happens if the .auto.tfvars is removed temporarily.
f
@little-author-61621, that would make more sense actually 🤔
@little-author-61621, I was able to fix the error as per your suggestion, however now it seems it doesn't calculate the cost difference, code:
Copy code
stage(name: "infracost-base.json - production") {
                        
                        sh """
                        export INFRACOST_API_KEY=${JENKINS_INFRACOST_API_KEY}
                        
                        git checkout master

                        infracost breakdown --config-file /tmp/base/infracost.yaml --format json \
                                --out-file /tmp/base/infracost-base.json
                        """
                    }

                    stage(name: "Infracost - Compare Costs"){
                        sh """
                        export INFRACOST_API_KEY=${JENKINS_INFRACOST_API_KEY}
                        
                        git checkout ${env.BRANCH_NAME}

                        infracost diff --config-file=/tmp/base/infracost.yaml --format=json \
                                --compare-to=/tmp/base/infracost-base.json \
                                --out-file=/tmp/base/infracost.json
                        """
                    }

                    stage(name: "Infracost - Push Costs (PR)"){
                        sh """
                        infracost comment github --path=/tmp/base/infracost.json \
                                --repo="TAKEALOT/${githubRepo}" \
                                --pull-request="${githubPullRequestNumber}" \
                                --github-token="${GITHUB_TOKEN}" \
                                --behavior=update
                        """
                    }
