workflow:run rejects "environment" field on update jobs despite schema/docs allowing it

[AmitRDesai]

Build/Submit details page URL

No response

Summary

• environment on update job type causes: Invalid workflow definition. [jobs]: Invalid input: expected record, received undefined
  • eas workflow:validate passes locally (CLI v18.0.1), but the server API rejects it
  • environment works fine on fingerprint jobs, only fails on update jobs
  • Request ID: 7bb69830-4069-4aa5-97ea-cbd3b319f41d
  • The published JSON schema at api.expo.dev/v2/workflows/schema explicitly lists environment as valid for update jobs
  • Removing environment from update jobs resolves the error
