how to handle multiple optional query params?

[Shasi1]

Hi,

I am using ExtractVariables and then AssignMessage Policy to set query params in the request from the extracted variables.

I have query parameter being set in Assign Message Policy. It works fine if I pass all the query parameters in the request. If there are multiple optional parameters and if I don't pass them in the request, then I see invalid arguments error. How can I handle this when request doesn't send optional parameters.
