Error in device formation using bulk

[hsuya]

I was trying to make a device however I got this error. I am unable to understand what went wrong because it is working fine with other structures.

Traceback (most recent call last):

Please provide the script and log file related to this calculation/error.

It happened in builder when I was trying to make a device so there was no calculation error. The device did not form and instead I received this error.
