A pipeline is pending, I just want to continue without any parameters, so I use pipeline API to check process, but it will be returned an error: "parameters is required".

Now the request body like :

{"id":"2", "parameters":[]}

it works well, but the field "parameters" is not used.

I guess If we remove "parameters" like {"id":"2"}, The function can also work well.
Perhaps support both different struct is a better choice.
