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

6.12.4 (latest)

Ajv options object

{ strictKeywords: true }

JSON Schema

{ "type": "array", "items": false }

Sample data

[1]

Your code

const Ajv = require("ajv");

const ajv = new Ajv({ strictKeywords: true });

ajv.validate({ type: "array", items: false }, [1]);

console.log(ajv.errors);

Validation result, data AFTER validation, error messages

null

What results did you expect?

same validation error as when strictKeywords is false or "log"

[
  {
    "keyword": "false schema",
    "dataPath": "[0]",
    "schemaPath": "#/items/false schema",
    "params": {},
    "message": "boolean schema is false"
  }
]
