My code crashes when I press a button

Whenever we push the button to activate our command the robot disables itself and we get a null pointer exception.
(here’s the github)

The exception message should tell you which line it came from. See what variable was null, and find out why it wasn’t initialized.

The variable is being initialized in constants.
The variable is SHOOTER_SPEED

What’s the full line of code? A double variable can’t be null. NPEs occur when you try to do a.something() when a is null.

We found the issue, it was a typo where we were executing the command. We got it fixed now though. Thanks for the help!
