How do you validate a JSON Schema?
The simplest way to check if JSON is valid is to load the JSON into a JObject or JArray and then use the IsValid(JToken, JsonSchema) method with the JSON Schema. To get validation error messages, use the IsValid(JToken, JsonSchema, IList ) or Validate(JToken, JsonSchema, ValidationEventHandler) overloads.
What is JSON Schema in MongoDB?
JSON Schema is an IETF standard providing a format for what JSON data is required for a given application and how to interact with it. Applying such standards for a JSON document lets you enforce consistency and data validity across similar JSON data.

When did MongoDB start validating JSON Schema?
From Version 3.6, MongoDB supports this standard and provides a JSON Schema Validator from within the application that runs like a trigger to check any changes to the data via inserts or alterations.

What happens if validationaction is error in MongoDB?

If the validationAction is warn, MongoDB logs any violations but allows the insertion or update to proceed.
How to determine why a MongoDB document is?
As at MongoDB 3.2, there is no feedback on the reason document validation failed: the overall validation expression currently evaluates as either True (“OK”) or False (“Document failed validation”).
