Hello. 🍣

The type it seems {} as Object by this.response.body.constructor.name.
But in this case, it seems [] as Array by this.response.body.constructor.name.

I tried changing lang on Editor component's prop.Modify responseType by Object(json) or Array(json5)

• json => displays error x.
• json5 => displays no errors.

So I modified by using json5 when the response body is Array.
(json when is is Object)

I'll make PR later.
