The chain of event are:

• Activity is executed
• Client Request fail to enrich
• Request goes to server
• Response comes back
• Client asserts the Response and fail
• Exception shown to user is the failed Client side Assertion.

The real cause of the failure is the failed serialization of the enrichment object to setup the server side, which cause the server side response to be wrong and client assertion of course failing.

Two things odd here:

• Enrichment problems are hidden
• Request still goes to server even tho we couldn't fulfill the setup
