codeql-action/upload-sarif@v1 doesn't accept empty sarif

Reproduce el fallo con el ejemplo SARIF vacío y, a continuación, empieza en lib/upload-lib.js en la ruta de upload indicada y sigue su llamador en lib/upload-sarif-action.js. Confirma que un array runs vacío se completa sin el error 422 mostrado y añade o actualiza la cobertura allí donde se pruebe el comportamiento de upload.

Expected behaviour:
No error

Actual behaviour:
codeql-action/upload-sarif@v1 doesn't accept empty sarif

Exemple:

{
  "$schema": "https://schemastore.azurewebsites.net/schemas/json/sarif-2.1.0-rtm.5.json",
  "version": "2.1.0",
  "runs": []
}

Result:
