The official ngx_eval module can only work with content handlers that
explicitly support the "nginx subrequest in memory" feature. Just a
few modules support that, like ngx_proxy, ngx_memcached, and ngx_memc.
My ngx_echo does not support it, nor does ngx_fastcgi.

You can try out my fork of ngx_eval instead:

But as the README page of my fork has already says, it's recommended
to use ngx_lua to do such tasks because it is more flexible and more
reliable.
