Wcf 400 bad request We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. I have created a sample wcf application and just run it on asp. Mar 30, 2017 ยท The service can return JSON. 2. Mirth is Java-based, uses Mule internally which uses JAX-WS. 2. WebFaultException is a FaultException and therefore can be used as the fault exception programming model for services that expose SOAP endpoints as well as web HTTP endpoints. I made a simple WCF Service and a client to upload file. , but there is something wrong with the configuration, you would still get the 400 Bad Request since a default endpoint would be created and used. Content-Type is set to application/json. vhqw xra jaitdr fhd okqd vsxz onie rebuub qdm yxq dzdrtc kgwv weob wtg hbkjro
