I followed the instructions from here: Creating a New Filebeat Module | Beats Developer Guide [master] | Elastic.
make create-module MODULE={module}
make create-fileset MODULE={module} FILESET={fileset}
make create-fields MODULE={module} FILESET={fileset}
All the commands above worked except for make update.
This is what I see when I run make update in cmd
mage update
>> Building filebeat.yml for linux/amd64
>> Building filebeat.reference.yml for linux/amd64
>> Building filebeat.docker.yml for linux/amd64

Any help will be appreciated
