Download this file and replace Azure credentials at the top.

Then run

dep init
go run ./azure-sdk-filter.go

It should panic with a similar error

resources.GroupsClient#List: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="InvalidFilterInQueryString" Message="Invalid $filter 'name eq 'foo'' specified in the query string."
