[mholt]

This is an unfortunate bug in the Go toolchain:

golang/go#56494

Allegedly it will be fixed in the next release of Go.

[coolaj86]

What version of Go can I use that does work?
(I can easily switch versions a la webi [email protected])

[mholt]

I don't think any currently-released version of Go has a fix.

I don't remember the details at this point, but you might try using --with github.com/caddyserver/caddy/v2=github.com/caddyserver/caddy/[email protected]

Or updating the Caddy version in this module's go.mod, I can't remember if one of these worked or if that was for the other Go bug.
