I'm trying to do the following:

Try: invoke CFC_A, which includes qry.cfm, which invokes CFC_B

Could not find the ColdFusion Component or Interface cfc_path_here
- Ensure that the name is correct and that the component or interface exists.

In production, it doesn't work whereas on my local dev it works. Obviously,
it's a server configuration thing, I'm just not sure what it actually is.

In some cases, replacing the full cfc path, by just the cfc name instead
resolved it. This was where CFC_A would invoke CFC_B (without the *.cfm
middleman).

It sounds like you have a custom tag path or a CF mapping missing.

Posting - rather than paraphrasing - the error might help. As well as
posting - rather than describing - the code.
