Invalidate Content Error

[Naama Shoresh]

Hi,

When trying to invalidate content from the TO UI, I get the following fatal
error message:

Traffic Ops fatal error occurred while processing your request.
------------------------------

In traffic_ops log file I see this message:

Any idea why this happens?

Thanks,
