API error with Module development

I am developing a module, trying to use $modx->config[’base_path’] to load a config file.
the module executes, but generates a runtime error
in the system events log it says:


is there a different call I should use. I tried $modx->config[’site_url’] and $modx->config{’base_url’].
neither of those calls generate a runtime error, but both generate PHP errors relating to the file not existing.

I am developing under MODx 0.9.5 beta (rev 1392).

If this is a bug under that revision, I will upgrade, but I would rather not potentially add more problems at this point.
I am sure I am just missing something simple.

I just tested on a local install of MODx 0.9.5 beta 3 (rev 1533) which produced the same runtime error:


the event log shows the same:


The module executes correctly so far, it just generates this error. I am not sure why because the undefined variable "base_path" gets the right file? either this is weird or I am dumb (probably option B).

any ideas?

Undefined variable base_path was a variable in the config.inc.php file that was being loaded.
all I had to do was define it in my module.
