Field 'MortgageId' doesn't have a default value in "Write Record" smart service

Did you check the log file tomcat-stdout.log for any additional details?

It seems that I haven't got access to tomcat directory:

It's in the base log directory. Not inside the tomcat folder.

Sorry, I am newbie in Appian. I paste you some errors of tomcat-stdOut.log around the hour that my "Write record" failed:

This is an odd error. Is this in your dev environment?

This is an odd error. Is this in your dev environment?

Yes, the error is very weird. Finally, I solved it doing something like this:

Basically, I replicate the behavior of the "Write Record" smart service with the above sequence of smart services.

That's a bad idea. The internet is full of error message like yours. I highly recommend to fix the root cause instead of working around it.
