Hey, know that joke where people say it runs yesterday but for some reason it doesn't run the next day? The same thing happens to me here with Hecker (a Hacker News 'client' written in Go that I am currently working on)... Oh wait a second it works again!

Btw, if you care about this, then the error seems to be a JSON error, which means that one of the submissions the program scrape has wrong JSON format, and its error is an invalid character error. Bruh.
