PatchDocumentsResponse is the model representing one object from the response when updating multiple document. In case of error, the response returned by ArangoDB contains the errorMessage property. However PatchDocumentsResponse doesn't contain an equivalent ErrorMessage property.

Example:

[ { "error": true, "errorNum": 1205, "errorMessage": "illegal document handle" } ]
