New bug in v1.4.0-1, path.lua:501: attempt to concatenate a nil value

/usr/local/share/lua/5.1/pl/path.lua:501: attempt to concatenate a nil value
stack traceback:
/usr/local/share/lua/5.1/pl/path.lua:501: in function 'expanduser'
/usr/local/share/lua/5.1/resty/aws/config.lua:240: in function 'load_config'

Hi this is a new issue we have encountered in your recent update 1.4.0. Seems to be caused by the change at resty/aws/config.lua:240, where you call pl_path.expanduser(env_vars.AWS_CONFIG_FILE.value).

@rushikeshz97 on what platform are you experiencing this? Looks to me that issue could only occur on Windows?

Have you tried setting up Nginx such that the HOME environment variable does not get cleared? (when Nginx forks its worker processes, by default it will clear the env vars for security reasons)

Hmm, a failure example after version bump also found here: https://github.com/Kong/kong/actions/runs/8627721759/job/23648513062?pr=12846

It seems we need a penlight bump to solve the issue? (We might need to pin penlight version in dependency list to >= 1.14.0)

[Tieske]

yes, we'd need that. I have an open PR to check, and then I can probably cut a Penlight release.

Are there required timelines?

@Tieske We'll need this before the feature freeze of 3.7 of Kong gateway which should be 2 weeks later.

Penlight 1.14.0 has been released and should fix the issue. Closing this now. @rushikeshz97 please reopen if necessary.
