    On first iteration, body equals the correct body from response (b'<HTML CONTENT>'), on second iteration body is empty (b''). This empty body is use on the subsequent code, inserted on response, but line 97 never occurs.

    *** TypeError: Object of type UUID is not JSON serializable

    I suggest, adding UUID serialization, by cast to str

    Add reviver parameter on JSON.parse redefinition

    This solves Issue #13 that explains how the reviver parameter is excluded from the JSON.parse redefinition. This causes errors when trying to decode parameters using the openapi module contained in the FastApi framework.

  • JSON.parse collision with fastapi openapi module

    JSON.parse collision with fastapi openapi module

    I've experienced collisions on the JSON.parse function. When using the fastapi-debug-toolbar and /docs on fastapi which uses openapi module.

    refresh.js file redefines JSON.parse functions, excluding the reviver parameter. This cause issues on the function on get_swagger_ui_oauth2_redirect_html() function on file https://github.com/tiangolo/fastapi/blob/master/fastapi/openapi/docs.py.

    JSON.parse is used on L140:

    qp = qp ? JSON.parse('{' + arr.join() + '}',
                        function (key, value) {
                            return key === "" ? value : decodeURIComponent(value)
                        }
                ) : {}
    

    that uses the reviver function. The original implementation is not executed, but your overridden function, which does not include the reviver function which causes issues on encoded URI character not being properly decoded.
