How to deal with errors in dev

[PaulRudin]

I'm experimenting with Hono using some code for Fastly's compute service. Formerly I was using Expressly and someone recommended that I try Hono instead.

I've modified my Expressly code, made a new project using npm create hono@latest ... and then started the dev server with npm run dev. So far so good.

I then fire a request at the dev server and I see: Error: (new TypeError("t is undefined", "<stdin>", 919)) with no stack trace. Obviously it's hard to figure out what in my code is triggering the error - there's no variable called t anywhere in my code - so presumably this is from minification?

Anyway - is there a way to get more useful context for the error? TIA.
