Hi all,

I try to break down one large serverless.yml file into smaller manageable ones and include them with $file(PATH\_TO\_FILE)  
serverless.yml includes a number of

- environment setting files
- templates per functions
- model documentation parts

all together we have 48 files included and works fine.  
however when I add one more file I get the error message bellow , regardless I  
include a documentation or a template file.  
The same include that breaks the service works perfectly fine if I remove any others , reducing the number of files .  
Did anybody face similar problem? Could be a kind of limitation on size or number of files ?

TypeError: **Cannot read property ‘shift’ of undefined**
