"Message inspection failed" Error when using QMS API

By using the QMS API Client available in the QlikView Power Tools, the specific QMS API can be called outside of the custom code to verify there is no issue with the API itself.

The QMS web service requires the presence of a HTTP header containing a “service key” representing your user session with the server. This must be injected into every request and while this is a fairly complex thing to do, QlikView provides the code required to do this in .NET projects. More information can be found in Qlik Community: https://community.qlik.com/docs/DOC-3647

This error can occur if not allowing enough time between each step in the client code. E.g. Creating the source document and immediately calling the APIs to create an associated task for it.


 

The issue can be resolved by implementing a sleep thread that checks for a documents existence before creating the task. This also results in the custom code calling the API fewer times. 

More time should be allowed between each step. E.g. Creating the source document and allowing some time before calling on the APIs to create an associated task for it.
