Incorrect validation with `paramStructure === "by-name"`

[pilot114]

Describe the bug
When calling method in js client, like

  let empId = 4026;
  const result = await client.getHistory(empId);
  console.log(result.total)

i have error

the problem is probably here

what's the point of validating params if we send rpcParams?
we need to check the schema of what we are sending.
