Cannot open shared object file?

[Avent37]

I'm trying to implement your plugin. I ran into the issue stated in Issue #1, and made the necessary changes. I then started the Kong API and got this error.
Please guide me on how to proceed further.

This is my configuration

I didn't add libinjection in my system library path. Issue was fixed after adding it.

Unfortunately, I'm now running into 500 Internal Server Error when I send a GET request.

1. Download the repository from GitHub
2. Enter the src directory.
3. Open a terminal, change directory to the src folder, and run the make command. This will generate a few object files and the main shared object file (called libinjection.so) required for the function of the plugin.
4. In /usr/local/lib, create directory called ‘libinjection’ and then copy the contents from the ‘src’ sub-directory of the original repository and paste it in the newly created libinjection directory.
5. Change directory to /etc/ld.so.conf/ and copy the libc.conf. file, rename it to libinjection.conf (it’s necessary prefix to be lib), and change it by adding the path of the libinjection folder , i.e. /usr/local/lib/libinjection
6. Once edited, save it, and run ldconfig on the terminal. Check if libinjection.so is now set up by running ldconfig -p | grep libinjection.so in the terminal.

I used lualocks make to deploy Kong_ The injection plug-in always reports attempt to index local 'handler' (a Boolean value) when I start. Can you give me some guidance? thank you.

Is this plug-in compatible with version 1.4.2? Looking forward to your reply, thank you
