AWS Documentation: https://docs.amazonaws.cn/en_us/step-functions/latest/dg/amazon-states-language-intrinsic-functions.html#asl-intrsc-func-json-manipulate

Other Information
We could use States.JsonMerge like below, but syntax check fails when running cdk deploy .
We have to change some code to make it passed.
TaskInput.fromJsonPathAt('States.JsonMerge($.json1, $.json2, false)')
