loading feed crashes with fileBaseUrl in macros/modules section

[garret1317]

"Rolling" Variables: These variables can be defined at any depth in the JSON tree and are continuously expanded using the variables available. You can reference a rolling variable in itself, which will substitute the template for the contents the variable had at the parent-level.

Right now there's only one such variable: fileBaseUrl, which you can use to construct the URL to a file using the template variables available.

I have a fileBaseUrl in the macros section (and will put one in the modules section once I've got one), so I can store macros and modules differently
When DepCtrl tries to read my feed it throws the following error:

Lua reported a runtime error:
