[Feature Request] More details on errors in "info" output

[VegethB]

Is your feature request related to a problem? Please describe.
Upgrading to 0.27.0 (and then RC 27.1) I noticed this new error.
The problem is that you don't understand which XML it refers to until you start mango in Debug output and see which file it is reading

Describe the solution you'd like
Specify on which file the error occurred.
Like, it's processing the config.yml and there are syntax errors, the info output will tell me that an error occurred on that file.

Describe a small use-case for this feature request
If it weren't that the error was on line 187, I would have been 20 30 minutes figuring out where it was in the config.yml

Additional context
