Descriptions

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version 4.10.3, Parse Server crashes when if a query request contains an invalid value for the `explain` option. This is due to a bug in the MongoDB Node.js driver which throws an exception that Parse Server cannot catch. There is a patch for this issue in version 4.10.3. No workarounds aside from upgrading are known to exist.

Parse Server es un backend de código abierto que puede ser desplegado en cualquier infraestructura que pueda ejecutar Node.js. En las versiones anteriores a 4.10.3, Parse Server se bloquea cuando una petición de consulta contiene un valor no válido para la opción "explain". Esto es debido a un bug en el controlador Node.js de MongoDB que lanza una excepción que Parse Server no puede atrapar. Se presenta un parche para este problema en versión 4.10.3. No se conocen soluciones aparte de la actualización
