json-schema-patterns-valid

This rule checks regular expressions used by JSON Schema keywords such as pattern and patternProperties.

JSON Schema patterns use ECMA-262 regular expression syntax.

Bad example

{
  "type": "string",
  "pattern": "["
}

Good example

{
  "type": "string",
  "pattern": "^[A-Z]{3}$"
}

How do I fix this violation?

Fix the regular expression syntax.
