Hello All,

I am working on BizTalk 2020 migration project. One of the BizTalk application migrated to BizTalk 2020 is not running and I am getting below error message in event viewer. Can someone please guide me about this error message. I have gone through lots of forums but didn't find much on this.

*xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'MDR.PARS.MDMONODS.Orchestrations.ProcessStartMDM(bfdde059-36df-c705-b865-07f37913c17d)'.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

    Hi,

    Aha. Then I think you're missing the "SecureAppSettings" in the BizTalk app config.
    That's why you're getting the NullReferenceException:Object reference not set to an instance of an object..

    I guess you had it on the old server.

    Hi,

    What kind of Shape is the "Initialise Credentials" shape?

    Is it an Expression shape? What expression / code does it contain?
