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 Kamlesh,
Yes it is a DEV environment. I tried to debug the orchestration and yes for some of the variable it is coming NULL values. But I am not able to identify from where it is coming and for which variable. Can you pls guide on how to debug orchestration better. Or is there any link or videos.
Hi Rohit,
For Orchestration debugging please refer to MS Doc link to get the full understanding.
https://learn.microsoft.com/en-us/biztalk/core/debugging-orchestrations
And as Leo pointed, you have a config missing issue, please copy your required details from the old server to the new server and test it.

Thanks Kamlesh,
I will go through the link provided by you to understand orchestration debugging. Also can you answer my below query I just posted.
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.
Br,
Leo
Yes I checked it is there is old app server. But I am not sure how can I get those "SecureAppSettings" in config file of new servers. Do I just need to copy paste from old config files or somewhere I need to configure those so that it will reflect there.
And also there is lots of other stuff in config file of old server. How can I get those all in new config file.
Yes, copy paste.
Can I copy other stuff also which I require.
Well, that depends on what 'other stuff' is ;)
But your current error should be resolved if you move the config I mentioned.
HI Leo,
Thanks the issue got resolved. I moved little bit further. But now I am getting below error message in event viewer, What do I need to check??

HI Leo,
IThe issue got resolved now thanks. I was able to move little further. But I am getting below error message in event viewer.

Event ID: 0
Message: There is no value associated with the property 'MDR.Common.ODS.Schemas.PropertySchema.ods_interface_run_id' in the message.
There is an expression shape and it is getting this ods_interface_run_id value from SQL server, but I guess it is not able to fetch that value.
Hi,
What kind of Shape is the "Initialise Credentials" shape?
Is it an Expression shape? What expression / code does it contain?
Br,
Leo
HI Leo,
IYes it is the expression shape and it contains following expression.
//initialise credentials
credentials=(System.Collections.Specialized.NameValueCollection)System.Configuration.ConfigurationManager.GetSection("SecureAppSettings");
username=credentials["username"];
password=credentials["password"];
