"Error when processing request" after import account from csv

"Error when processing request" after import account from csv

Hi Team,

Now I use SDP MSP. In Incident template, i have one called "New Incident". This template worked correct.
This morning, I imported 100 accounts from csv with no error. 
And then, i go to Incident Template > click on "New Incident", the error notified as screenshot.





Please help me to fix this issue.
