Hi, thanks for putting this tool together. I tested it out using the public server, and ran into the output:

Error from CI backend. invalid json response body at https://builder-dot-lighthouse-ci.appspot.com/ci reason: Unexpected token < in JSON at position 0

Thinking it was a problem with the public server, I deployed a Docker container as described in the docs. The container had the same issue, though.

So I manually ran the curl command as so:

curl -X POST \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: $LIGHTHOUSE_API_KEY" \
  --data '{"output": "json", "url": "http://example.com"}' \
  https://<container url>/ci

And I got the output:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Error: ENOENT: no such file or directory, stat &#39;/home/chrome/reports/report.1544322152932.json&#39;</pre>
</body>
</html>

Perhaps something changed in the way Lighthouse generated its reports?

Of course, I can't reproduce when I run the Docker container locally 😩

Aha, so this appears to be the error output in the container. Looks like "no usable sandbox, please update your kernel." If this is happening in my own container, maybe it's happening in the public one too?

Just occurred to me that, for my container anyway, the problem is probably that it's not running with --cap-add=SYS_ADMIN as specified in this repo's README.

Oddly, even after fixing the SYS_ADMIN issue and verifying that the curl command to /ci works correctly, the lighthouse-ci command still fails in Travis. (nolanlawson/pinafore#793)

Since the proximate cause is that the client expects JSON and is getting HTML (probably an error page), maybe this is the same issue happening for the main lighthouse-ci server?
