Empty key is not validated by "required" keyword

[hosekp]

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

8.11.0

Ajv options object

Without options

JSON Schema

{
   "$schema":"http://json-schema.org/draft-07/schema",
   "type":"object",
   "properties":{
      "": { "type": "number" }
   },
   "required": [ "" ]
}

Sample data

{}

Your code

  const ajv = new Ajv();
  const validate = ajv.compile(schema);
  console.log("Broken example",validate(data))

Validation result, data AFTER validation, error messages

No errors

What results did you expect?

I expect an error about missing "" property

Are you going to resolve the issue?

I have found a workaround. If you use loopRequired=0 option, it is working.

an interesting edge-case - this is indeed a bug.
