Weird error

The console doesn't let me scroll up (weird in itself) so I can't show everything that's happening, but this is the error I get. Note: other people have gotten the same error, asked the same question, and were given answers that I did. I had already done them early in the course, but then I went back and did them again (copying and pasting the code provided in the answer to migrate) and it still doesn't work.
