title: Why am I getting a Travis CI error on my pull request to add a schema to a file?
body: <p>I am new to Github. I don't usually program, but I'm trying to do something for the Google Code-In here. I submitted a <a href="https://github.com/xsf/xeps/pull/327" rel="nofollow noreferrer">pull request</a> with several changes to xsf/xeps on Github, but I'm getting an <a href="https://travis-ci.org/xsf/xeps/builds/184991280" rel="nofollow noreferrer">error with Travis CI</a>. The end of the log with TCI looks like this:</p>

  <p>What's going on here?</p>
  
  <p>Okay, I'm editing this to add that I've tried what @melpomene suggested in their answer below. However, I've tried to remove that line 4 times and then re-squashed the commits after, and it keeps re-appearing. How do I fix this?</p>
