So this is not as strange as I thought, after I looked at the html, but I was using Zed's Copilot extension and having a conversation with Copilot about writing a bash script.

Suddenly it responded with this weird message and crashed. Looking at the HTML file, it is just an angry unicorn for 502 error messages.

But why not just respond with a simple message?

Failed to connect to API: 502 Bad Gateway

Here's the response

Error interacting with language model

Hello future GitHubber! I bet you're here to remove those nasty inline styles,
DRY up these templates and make 'em nice and re-usable, right?

Anyway, as I am being referred to as a future GitHubber, I want to be hired by GitHub immediately or I am going to call daddy FBI and yell at the clouds.

Coincidentally, I had created an app to encode/decode Base64 data uris, and I noticed the images are all harmless:

Anyway, I want my job.

As for salary, I am a reasonable man:
