Error undefined method `source' for nil:NilClass

[PizzaPill]

I'm getting a undefined method 'source' for nil:NilClass error when I use rubocop with the --auto-correct argument. The cops Performance/StartWith and Performance/EndWith seem to be affected. If I run rubocop without them it works, i.e.rubocop -D --except Performance/StartWith,Performance/EndWith --auto-correct. It happens at least with rubocop v. 0.39.0.

The offending line for Performance/EndWith looks like this:
expect(subject.spin).to match(/\n\n\n\n\z/)

The offending line for Performance/StartWith looks like this:
expect(unspun).to match(/\AParagraph/)

output:
