LabVIEW HTTP POST VI Error: "cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher"

[Anthony_L]

This error just started happening on a different SOAP Server Service:

"cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher"

Other Server URLS work OK

Any pointers to fix this from :LabVIEW HTTP client end?

This has been resolved.

I wrote this article as a solution pointer.

HTTP POST Headers for WITSML LabVIEW Client

Implementing WITSML in plain LabVIEW code using HTTP VIs requires that the following Headers are added before running the POST function which sends the SOAP request packet.

Cache-Control = private

Content-Type =text/xml

charset = utf-8

SOAPAction = http://www.witsml.org/action/120/Store.<User WMLS_FUNCTION>

Where: <User WMLS_FUNCTION>

Must be replaced with any one of the following SOAP Action requests:

WMLS_GetCap
WMLS_GetVersion
WMLS_GetFromStore
WMLS_AddToStore
WMLS_UpdateInStore
WMLS_DeleteFromStore

Including these headers before running the intended LabVIEW HTTP POST method helps to ensure proper response from WITSML AGGREGATE servers.

Mezintel has deployed LabVIEW-based WITSML 1.4.1 client to multiple WITSML service providers by including these headers before each target POST method.
