Biff example site does not load: java.lang.ArithmeticException: long overflow

[dhazel]

Hi!

Thanks for the great project! I love that Biff is a quick option for getting started with Clojure webdev.

I am quite new to Biff and Clojure webdev in general, so if this is a noob question, then thanks for humoring me :)

My system info is as follows:

• OS: Fedora 39
• Java: openjdk 17.0.9 2023-10-17
• Clojure: Clojure CLI version 1.11.1.1435

When I follow the getting started instructions, found here, after running clj -M:dev dev, then every time I hit the site at localhost:7888 I am seeing the following error repeated in the console:

ERROR:

This looks similar to an error reported in the nrepl repository.

I wonder if there is a fix or a work-around for it for Biff?

Hi! I think this is the problem:

every time I hit the site at localhost:7888

You need to go to localhost:8080 in your browser; port 7888 is only meant to be used by your editor's nrepl plugin. I get the same overflow error if I do curl http://localhost:7888.

Success! Thank you!!
