Default url query strings and error hints #27
Description
Error Hints
If there's any required url query string is missing, respond with some error hints that makes sense.
e.g.
This should respond with something like Parameter missing: dashboardId. instead. (Just like what we did on the feedback one: if the rating is missing or exceeded, some hints will be prompted.)
Default parameters
Even though I add the dashboardId, it still needs page and pageSize parameters. But I think these two should be optional as they can have default values 1 and 10 for example.
