@param.array {type: 'object'} throws 400

Steps to reproduce

In explorer, make a GET request to a controller that has an array of type: 'object': @param.array('objectArray', 'query', {type: 'object'})

Current Behavior

When making a GET request to a controller with an array of objects parameter @param.array('objectArray', 'query', {type: 'object'}), it will throw a 400 [{path: "/0", code: "type", message: "must be object", info: {type: "object"}}] because it doesn't parse the JSON string.

Example:
/getWithObjectArray?objectArray=%7B%22name%22%3A%22hello%22%7D
essentially parses to:
['{"name":"hello"}']

Expected Behavior

The request should parse the json string in each array item so the request does not fail.

Added a test to show it broken: https://github.com/kyle-apex/loopback-next/commit/3d9d8e602f8a747e63ced1cf443f92a59998f35f

Added some code to show it "fixed": https://github.com/kyle-apex/loopback-next/commit/0a69964708fe2f135acd47900d86636dc199a515

My "fix" may be too broad. In openapi-v3/../parameter.decorator.ts, @param.query.param forces content: { 'application/json': { schema, }, } so coerce-parameter.ts knows to parse the JSON. @param.array doesn't have a similar capability, so it's tough for coerce-parameter.ts to know if it should parse the object represented as a string as JSON or not.

Any ideas for best approach?

Bắt đầu bằng việc tái hiện một yêu cầu GET sử dụng @param.array với type: 'object', sau đó kiểm tra openapi-v3/../parameter.decorator.ts và coerce-parameter.ts để hiểu cách nội dung JSON được chọn. Hoàn thành khi mỗi chuỗi đối tượng JSON trong mảng được phân tích, để yêu cầu không còn thất bại với phản hồi 400.
