Unable to sync due to a system failure.

Hi, I'm facing the issue while executing a process.

When I ran a process it'll insert data into database. The process is working in DEV & I deployed the code in test and tried to run the process but the record sync is failing. I can see the data is inserted into table but node is failed. Also, I tried to sync manually, it's still failing. 

I found the below from logs, but not much help. If anyone have idea on how to resolve this error.
