Express 5 req.query immutable #969
Description
The request parameter mutator is broken when express 5 is used
When you have a query parameter definition for array values, the req.query[key] could not be updated because it is immutable in express 5.
The req.query key values are not parsed by its query parameter definitions in the OpenApi 3 specs
The req.query parameters should be parsed like defined in the OpenApi 3 schema for the query parameter
Example sort query parameter definition:
name: sort
in: query
description: Sort parameter
required: false
style: pipeDelimited
explode: false
schema:
type: array
items:
type: string
req.query = { sort: "name|date"} should be having an array value after parsing: req.query = { sort: ["name", "date"]}, but it remains the same value req.query = { sort: "name|date"}
