Cant' run tests, ./kong/pdk/init.lua:209: in main chunk

Installation/Setup
1

Hi all,

I’m just getting set up with kong for the first time. I’ve written my own plugin and want to run the tests in the spec folder. I’ve checked out kong, lua-resty-core and busted and have them all on the lua path and openresty in the bin path.

If I try run “make test” as per https://github.com/Kong/kong#tests I get this issue

Error → ./kong/pdk/init.lua @ 209
suite spec/01-unit/11-reports_spec.lua
./kong/pdk/init.lua:209: assertion failed!

stack traceback:

Plugins lazy_setup
…5.1/kong/plugins/my_custom_plugin/handler.lua:10: attempt to index global ‘kong’ (a nil value)

I’ve been stuck on this a while now and really could use some insight if someone has some. That issue that there’s an error on 209 is an openresty dependency issue but I can confirm is it’s int lua_path and path (bin path)

Not sure it will help but below is the full error when testing

You might be running into some weirdness with mismatched Kong and OpenResty versions. For instance, Kong 1.3 currently requires openresty 1.15.8.1 with Kong’s OpenResty patches applied. Also, the following comment:

attempt to index global ‘kong’

Suggests something might be going wrong with your lua path, such that it isn’t picking up init.lua within the kong/ directory of the repo. I wonder if they who wrote the instructions for this unit tests have ./ and ./?/init.lua as part of their lua path implicitly?
