Schema validation with Ajv

[
  {
    keyword: 'type',
    dataPath: '.features[0].geometry.coordinates[0]',
    schemaPath: '#/properties/features/items/properties/geometry/properties/coordinates/items/type',
    params: { type: 'array' },
    message: 'should be array'
  }
]

Why Ajv detects an issue ?

Thx
