Ensure you have provided the following details while reporting a problem:

• The exact version of the related software, including but not limited to the OpenResty version
  (if any), the NGINX core version, the ngx_lua module version,
  and your operating system version.
• A minimal and standalone test case that others can easily run on their side and
  reproduce the issue you are seeing.
• Do not simply say "something is broken" or "something does not work". Always provide
  as much details as possible. Always describe the symptoms and your expected results.
• You can (temporarily) enable the nginx debugging logs to see the internal workings
  of NGINX in your nginx''s error.log file. See http://nginx.org/en/docs/debugging_log.html
  The same instructions apply equally well to OpenResty.
• If you are seeing crashes, please provide the full backtrace for the crash. See

My openresty version is 1.13.6.2, but I cannt use ngx.shared.dict:free_space() in it,
while I have seen that it was supported in 1.13.6.1。

error.log:
lua:10: attempt to call method 'free_space' (a nil value)

version:
nginx version: openresty/1.13.6.2
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013

Show the full code. Likely you just call method on the value that is not a dictionary.

@huzhewei
Have you called require "resty.core.shdict"as the doc suggests: https://github.com/openresty/lua-nginx-module#ngxshareddictfree_space?
We need a reproducible example, otherwise we can't offer you any help.

thank you @spacewander , it's all my fault !
I think that I didnt read the doc carefully and missed the [ require "resty.core.shdict" ].

Best wishes to you @decadence @spacewander !
