minProperties and removeAdditional does not collaborate well

[moontai0724]

What version of Ajv are you using? Does the issue happen if you use the latest version?

latest (8.17.1)

Ajv options object

{ removeAdditional: "all" }

JSON Schema

{
  "type": "object",
  "minProperties": 1,
  "properties": {
    "foo": {
      "type": "string"
    },
    "bar": {
      "type": "string"
    }
  }
}

Sample data

const shouldError1 = {};
const shouldError2 = { foobar: "baz" };
const shouldPass = { foo: "bar" };

Your code
Validation result, data AFTER validation, error messages

const validate = new Ajv(options).compile(schema);

const shouldError1 = {};
console.log(validate(shouldError1), shouldError1); // valid = false, data = {}

const shouldError2 = { foobar: "baz" };
console.log(validate(shouldError2), shouldError2); // valid = true, data = {}

const shouldPass = { foo: "bar" };
console.log(validate(shouldPass), shouldPass); // valid = true, data = { foo: "bar" }

What results did you expect?

The object with only additional properties is expected to have error for not satisfy the minProperties constraint after additional properties has been removed.

Are you going to resolve the issue?

Currently not yet.
