Send 2 query parameters with the same name

Yes Postman response is OK - Exact what I expect - also both parameters in th APi Server Logfile. Since MAke is (according to the apach logs) not sending the right URL the response i s wrong
make is not adding the second Parameter…

also when i swicth OFF "Disable serialization of multiple same query string keys as arrays”
The URL is not modilated correctly !!! that is why i guess it is a bug
