JQ fails when affected stacks is empty

[brett-au]

Describe the Bug

When updating our atmos repo, if we do not touch any component, catalog or stack files JQ fails to correctly parse the output.

jq: error: syntax error, unexpected ';' (Unix shell quoting issues?) at <top-level>, line 1:
def name: ;          
jq: 1 compile error
Error: The process '/usr/bin/jq' failed with exit code 3

When I run atmos locally the output is [] as expected

➜  affected=$(jq -c '.' affected-stacks.json)

➜  echo $affected
[]
➜  echo $affected | jq
[]

we are running cloudposse/github-action-atmos-affected-stacks@v3 which calls this action

Expected Behavior

cloudposse/github-action-atmos-affected-stacks@v3 runs successfully and returns an empty set so if: ${{ needs.context.outputs.has-affected-stacks == 'true' }} returns false correct and doesn't run more jobs based on the matrix.

Steps to Reproduce

name: "terraform plan matrix"

permissions:
  id-token: write
  contents: read
  pull-requests: write

on:
  pull_request:
    types: [opened, synchronize, reopened]

env:
  ATMOS_LOGS_LEVEL: Off

jobs:
  context:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4

    - id: affected
      uses: cloudposse/github-action-atmos-affected-stacks@v3
      with:
        nested-matrices-count: 1

    outputs:
      affected: ${{ steps.affected.outputs.affected }}
      has-affected-stacks: ${{ steps.affected.outputs.has-affected-stacks }}
      matrix: ${{ steps.affected.outputs.matrix }}

Environment (please complete the following information):

@brett-au I can not reproduce the bug.

Can you provide full logs pls

[goruha]

@brett-au have you config atmos.yaml` for gitops correctly?

I'm getting the same error

I see the issue.

⨠ atmos describe config -f json | jq .
parse error: Invalid numeric literal at line 1, column 6

which fails because of these 2 outputs shown

⨠ atmos describe config -f json | head -2
Found ENV var ATMOS_BASE_PATH=/localhost/git/work/atmos
Found ENV var ATMOS_BASE_PATH=/localhost/git/work/atmos

This is because

# atmos.yaml
logs:
  level: Trace

I also tried setting ATMOS_LOGS_LEVEL and get the same error

⨠ export ATMOS_LOGS_LEVEL=Off
⨠ atmos describe config -f json | jq .
parse error: Invalid numeric literal at line 1, column 6

Options

1. Set log level Off in atmos.yaml and set ATMOS_LOGS_LEVEL=Trace in geodesic
2. or fix atmos to allow using an environment variable to turn off the Found ENV in the output
3. or update to strip out Found ENV from the output

I think I’ll just do (1) for now but I’d prefer (2) and (3) seems like a temp fix
