Dear All  
If it is possible I need an help about creation of a custom module for filebeat.  
I Followed the instructions

make create-module MODULE={module}  
make create-fileset MODULE={module} FILESET={fileset}  
make create-fields MODULE={module} FILESET={fileset}

All operation worked, I checked \_meta fields.yml and it is correct, but when I launch "make update"

## I have

```
mage update

There is a possibility to have a verbose compilation to found and solve the error?

best regards
