InfluxDB 2.0: The Expressions doesn't have defined a location [area/api]

[bednar]

The expressions are defined as:

ArrayExpression:
      description: used to create and directly specify the elements of an array object
      type: object
      properties:
        type:
          $ref: "#/components/schemas/NodeType"
        elements:
          description: elements of the array
          type: array
          items:
            $ref: "#/components/schemas/Expression"
    FunctionExpression:
      description: function expression
      type: object
      properties:
        type:
          $ref: "#/components/schemas/NodeType"
        params:
          description: function parameters
          type: array
          items:
            $ref: "#/components/schemas/Property"
        body:
          $ref: "#/components/schemas/Node"
    BinaryExpression:
      description:  uses binary operators to act on two operands in an expression
      type: object
      properties:
        type:
          $ref: "#/components/schemas/NodeType"
        operator:
          type: string
        left:
          $ref: "#/components/schemas/Expression"
        right:
          $ref: "#/components/schemas/Expression"

...

but in the HTTP response of an analysed query is also a location property:

-> POST 
-> http://127.0.0.1:9999/api/v2/query/ast
-> {
	"query": "from(bucket: \"telegraf\")\n |> filter(fn: (r) => (r[\"_measurement\"] == \"cpu\" and r[\"_field\"] == \"usage_system\")) |> range(start: -1d)"
