Fails to validate datetime string

[DrewMcArthur]

 EnforcerException: Invalid value
    at: timestamp
      Expected a valid date object. Received: "2025-11-24T22:52:03.329Z"

I'm getting this error validating a schema - using timestamp: new Date().toISOString(), is this a bug in the validation, or is toISOString not the right method to be using for a schema expecting:

timestamp:
  type: string
  format: date-time
  description: Current server timestamp
  example: "2024-06-01T12:00:00Z"

it seems like the enforcer is just expecting the response to contain a Date object, which I'm not sure I understand since any HTTP response will be JSON/strings (and the API spec itself specifies that this field is a string, with a datetime format, not a date). anyways, i was able to hack this fix:

Enforcer.v2_0.Schema.hook('beforeValidate', parseDateTime);
Enforcer.v3_0.Schema.hook('beforeValidate', parseDateTime);

function parseDateTime(
  value: string,
  schema: { type: string; format?: string },
  _exception: unknown
) {
  if (schema.type === 'string' && schema.format === 'date-time') {
    return {
      value: new Date(value),
      hasException: false,
      done: true,
    };
  }
  return {
    value,
    hasException: false,
    done: false,
  };
}

Based on what I'm looking at, I believe you're using the Schema object's validate function. That function expects a deserialized object. If you pass the value through the deserialize function first, then it will properly parse values into the expected format. You would then take that result and call the validate function.

Try that out and let me know if it works for you.

Also, I'm glad you found the hooks. That can be useful for some interesting edge cases.
