## gotchas

### What is error `cosmo failed: [string "..."]:62: cannot resume dead coroutine`?

If you call `cosmo.yield`, your function **must** return `nil`! If you forget
to return `nil`, you will see this cryptic error:

    Error: index.html -> html/index.html: cosmo failed: [string "..."]:62: cannot resume dead coroutine
    make: *** [Makefile:6: build] Error 1`

### What is error `calling 'load_cache' on bad self`?

    moon: .../local/openresty/luajit/share/lua/5.1/sitegen/common.lua:41:
    /usr/local/openresty/luajit/share/lua/5.1/sitegen/cache.lua:99: calling
    'load_cache' on bad self (table expected, got userdata) stack traceback:

Delete your `.sitegen_cache` file.
