Bitbucket pipeline heroku-deploy config var "Failed to replace env in config"
Asked by John Kreisher:

I recently had to change one of my app's dependencies to a private repo on AWS Codeartifact. In order to pull from this private registry, I am logging in via the AWS CLI in the pipeline script steps, which I am able to do. This gives me an auth token which I set as an env variable (CODEARTIFACT_AUTH_TOKEN) and applies to my .npmrc file. This all works during the initial build step of my pipeline.

```
@zuri-fertility:registry=https://artifacts-zuri.../
//artifacts-zuri.../:always-auth=true
//artifacts-zuri.../:_authToken=${CODEARTIFACT_AUTH_TOKEN}
```

The last step of my pipeline is using the atlassian/heroku-deploy:2.0.0 pipe, and I am unable to get the env variable to be referenced in this pipe. The echo directly before it correctly shows the auth token, but I can't get it to be referenced in the heroku-deploy pipe.

```
- step:
  name: Deploy to production
  deployment: production
  caches:
    - pip
  script:
    - if [ -e set_env.sh ]; then
    - cat set_env.sh
    - source set_env.sh
    - fi
    - echo $CODEARTIFACT_AUTH_TOKEN
    - echo "export CODEARTIFACT_AUTH_TOKEN=$CODEARTIFACT_AUTH_TOKEN"
    - pipe: atlassian/heroku-deploy:2.0.0
      variables:
        HEROKU_API_KEY: $HEROKU_API_KEY
        HEROKU_APP_NAME: $HEROKU_APP_STAGING_NAME
        ZIP_FILE: cms-service.tar.gz
        CONFIG_VARS: >
          {
            "CODEARTIFACT_AUTH_TOKEN": $CODEARTIFACT_AUTH_TOKEN
          }
```

Here is the error that I get:

```
-----> Installing dependencies
Installing node modules (yarn.lock)
yarn install v1.22.19
error An unexpected error occurred: "Failed to replace env in config: ${CODEARTIFACT_AUTH_TOKEN}".
info If you think this is a bug, please open a bug report with the information provided in "/tmp/build_78066afc/yarn-error.log".
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.
-----> Build failed
```

I have attempted many solutions but can't get this variable to be loaded at the proper time for the yarn install to work during build time. Do you have any recommendations for me? Is the syntax of the CONFIG_VARS correct?

Thanks!

I realized I could run an "update" action step before trying to the deploy to production. This properly sets the config var in heroku. I am getting a different error, but this solves the initial issue so I'm closing this ticket.

Here are my bitbucket pipeline steps in case this helps anyone.

```
- step: 
  name: Set Codeartifact env variable
  script:
    - if [ -e set_env.sh ]; then
    - cat set_env.sh
    - source set_env.sh
    - fi
    - echo $CODEARTIFACT_AUTH_TOKEN
    - echo "export CODEARTIFACT_AUTH_TOKEN=$CODEARTIFACT_AUTH_TOKEN"
    - pipe: atlassian/heroku-deploy:2.0.0
  variables:
    HEROKU_API_KEY: $HEROKU_API_KEY
    HEROKU_APP_NAME: $HEROKU_APP_STAGING_NAME
    ACTION: "update"
    CONFIG_VARS: >
     {
     "CODEARTIFACT_AUTH_TOKEN": $CODEARTIFACT_AUTH_TOKEN
     }
  artifacts:
    - cms-service.tar.gz

- step:
  name: Deploy to production
  deployment: production
  script:
    - pipe: atlassian/heroku-deploy:2.0.0
  variables:
     HEROKU_API_KEY: $HEROKU_API_KEY
     HEROKU_APP_NAME: $HEROKU_APP_STAGING_NAME
     ZIP_FILE: cms-service.tar.gz
```

I am still getting this error:

```
error An unexpected error occurred: "https://artifacts-zuri.../@nestjs/common/-/common-8.4.7.tgz: Request failed \"401 Unauthorized\"".
```

On down the rabbit hole...

body: [@John Kreisher](/t5/user/viewprofilepage/user-id/4975534) hi. 401 means you can't pull from your private AWS Registry.  

You should determine in which step this error occurs. Please, provide detailed logs output, maybe I can help you.  

Regards, Igor
