Apologies if this has already been ask, but I wasn't able able to find an answer that works

I am having trouble validating a JSON Schema using an enum type with AVJ

I would expect the below code to return false, since the given value does not appear in the enum type

var Ajv = require('ajv');
var ajv = new Ajv();

var schema = {
  gender: {
    enum: [
      'male',
      'female',
      'other'
    ]
  }
};
ajv.validate(schema, { gender: 'test' });
// returns true

Are you able to let me know how to fix this please

In JSON Schema, all properties in the schema are directives called keywords. Unknown keywords are ignored.

In your schema, "gender" isn't a known JSON Schema keyword, so it's going to be ignored. You're probably looking for the "properties" keyword:

{
  properties: {
    "gender": {
      enum: ["male", "female", "other"]
    }
  }
}
