Secrets created by this lib are not readable by other github action workflows

[awkward-minion]

Describe the bug

• secrets are a way to manage and use them in workflows when required.
• When we tried to add secrets from the GitHub user interface (browser - webpage), they are accessible by any dependent workflows that use the newly created secrets.
• As part of automation, I have delegated the responsibility of creating and updating secrets to actions/github-script.
  • using github.rest.actions.createOrUpdateRepoSecret we are adding secrets to github
  • When tried to print to the output (stdout) in some dummy GitHub action using a workaround, we see the original secret value (with some spaces)
  • But when we tried to consume it, it is not readable or recognized by external scripts.

To Reproduce
Steps to reproduce the behavior:
Repository to reproduce the issue : here

1. Create a new workflow file test_secret_access.yml with the following content

   name: Verify
   on: [workflow_dispatch]
   
   env:
   AWS_REGION: "us-east-1"
   
   jobs:
   verify-secrets-access:
       runs-on: ubuntu-latest
       steps:
       - uses: actions/checkout@v2
       - uses: aws-actions/configure-aws-credentials@v1
           with:
           role-to-assume: ${{ secrets.DUMMY_AWS_IAM_ROLE_ASSUME  }}
           aws-region: ${{ env.AWS_REGION }}

2. Go to repository secrets
3. Add a secret with DUMMY_AWS_IAM_ROLE_ASSUME with a value, hello github
4. Run workflow test_secret_access.yml
5. Here aws-actions/configure-aws-credentials will be able to access secrets created manually.
6. Add create-secret.yml workflow with following contents

   name: Create
   on: [workflow_dispatch]
   
   
   jobs:
   create-secret-test:
       runs-on: ubuntu-latest
       steps:
       - uses: actions/github-script@v6
           with:
           script: |
               const publicKey = await github.rest.actions.getRepoPublicKey({
                   owner: context.repo.owner,
                   repo: context.repo.repo,
               })
               // assuming you will be actual secret from some API
               // encrypt the value using instructions here https://docs.github.com/en/rest/actions/secrets#create-or-update-an-organization-secret  
               const encryptedSecret = "dummy iam role with no access to zero resources"
               await github.rest.actions.createOrUpdateRepoSecret({
                   owner: context.repo.owner,
                   repo: context.repo.repo,
                   secret_name: "DUMMY_AWS_IAM_ROLE_ASSUME",
                   encrypted_value: encryptedSecret,
                   key_id: publicKey.data.key_id,
               })

7. After running the above workflow it will create a secret in the GitHub repo
8. Now try to run test_secret_access.yml, it will throw an error stating that It is unable to identify or access role-to-assume

Expected behavior
The secrets created using github.rest.actions.createOrUpdateRepoSecret should be accessible or readable to other github workflows.

This is not only happening with https://github.com/aws-actions/configure-aws-credentials.
This issue occurs to me when I tried to create secrets using github secrets API

@awkward-minion could you share how you're encrypting the secret?
