Problem

Release workflow failing at "Make devbox shellenv available" step. Manual printenv >> ${GITHUB_ENV} dumps all env vars including multi-line values (like Nix buildPhase), causing GITHUB_ENV parser error

Run eval "$(devbox shellenv)"
  eval "$(devbox shellenv)"
  printenv >> ${GITHUB_ENV}
  shell: /usr/bin/bash -e {0}
  env:
    NEW_TAG: v4.1.2
    latest_version: 0.18.4
    nix_version: 2.35.3
Error: Unable to process file command 'env' successfully.
Error: Invalid format '  echo " WARNING: the existence of this path is not guaranteed.";'

Solution

Use existing devbox-shellenv action that filters multi-line variables via env -0 parsing before exporting to GITHUB_ENV.

Testing

Successful Build
