Rake Task w/ ActionMailer - Undefined Method Error

I have a custom rake task and I am using a mailer with this task. I have an agent table with all of an agent's info. I also have an agent_card table that houses all of their license data. The agent_card table also has an agent_id column to identify which card goes with which agent. When trying to run the rake task and send out the mailer, I keep getting "ActionView::Template::Error: undefined method `name' for nil:NilClass." I can't figure out how to get the name, email, and phone through the agent_card table. I have included all the code below. Please and thank you!

Error:

rake aborted!

I figured it out. I was trying to use agent_card and didn't need it. Once I removed it, it works just fine!

@agent is not being passed through to the mailer or the value of it is being evaluated as nil.

The problem is not with your rake task or your mailer, figure out why the param is nil and that will solve your problem.
