Jira custom field module with resolver function fails

Hi Everyone,

I’m working with Jira custom field module(forge) with resolver function where actually I want to give options from api response to my field but deployment fails if I use resolver function in my manifest.

modules:
  jira:customField:
    - key: leo-hello-world
      name: Leo hello world
      description: A hello world custom field.
      type: string
      resolver:
        function: backendResolver
      edit:
        resource: main
        experience:
          - issue-create
          - issue-transition
          - issue-view
          - portal-request
        validation:
          expression: value == null || value != null
          errorMessage: The value must consist only of letters 
  function:
    - key: backendResolver
      handler: index.handler                 
resources:
  - key: main
    path: static/hello-world/build

            "__typename": "AppDeploymentTransitionEvent",
            "stepName": "Release Lambda functions",
            "createdAt": "2025-09-02T15:28:10.379Z",
            "newStatus": "DONE"
          },
          {
            "__typename": "AppDeploymentLogEvent",
            "stepName": "Save environment variables snapshot",
            "createdAt": "2025-09-02T15:28:40.392Z",
            "message": "Deployment failed with unknown error",
            "level": "ERROR"
          },
          {
            "__typename": "AppDeploymentTransitionEvent",
            "stepName": "Save environment variables snapshot",
            "createdAt": "2025-09-02T15:28:40.393Z",
            "newStatus": "FAILED"
          }
        ]
      }
    ]
  }
}
  Deployment failed with unknown error

Error: Deployment failed (requestId: 23c5daed-231d-4430-8e66-4f3314b18a25)

Note: if I remove resolver from manifest the deploy works just fine and with resolver forge lint doesn’t give any error but only deploy fails

I can’t use value:function as it is not compute function rather responses will be used in edit functionality

Any help much appreciated

Thanks,

Leo
