Breeze always 404 - http-status-code-404

Question

I built a oData-Service which works well.
Now I want to query them with Breeze but I always get an 404 error.
In Fiddler I see first a 200 with empty Body and then follows the 404 with "No HTTP resource was found that matches the request URI".
But running in a normal browser the odata Service delivers the right data.
I debug it and set a breakpoint on the Server to see if the service is called correctly. After sending the request the breakpoint shows that the Service is called. But parallel to the break breeze calls the fail-method of
manager.executeQuery(query)
.then(querySucceeded)
.fail(queryFailed);
and e.message is empty.
Any idea??? :-/

I deactivate CORS and now I get the 404 immediately.
Here is the request:
OPTIONS xxx:8080/myDataService/odata/Person?$select=Name HTTP/1.1
Host: xxx:8080
Connection: keep-alive
Access-Control-Request-Method: GET
Origin:localhost:61244
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.99 Safari/537.36
Access-Control-Request-Headers: dataserviceversion, accept
Accept: /
Referer: http://localhost:61244/index.html
Accept-Encoding: gzip, deflate, sdch
Accept-Language: de-DE,de;q=0.8,en-US;q=0.6,en;q=0.4
and here the answer:
HTTP/1.1 404 Not Found
Content-Length: 178
Content-Type: application/json; odata.metadata=minimal
Server: Microsoft-HTTPAPI/2.0
OData-Version: 4.0

{
"error":{
"code":"","message":"No HTTP resource was found that matches the request URI xxx:8080/myDataService/odata/Person?$select=Name'."
}
}

No surprise that the OPTION request passes; you've probably got the server set to say "OK" to every request ... and that's just fine for now.
The rejection has to do with the address of your GET request: xxx:8080/myDataService/odata/Person. Are you sure that's the right endpoint? The path is usually plural (Persons).
It's easy enough to just paste that url into a browser address bar and see what it does.
