serverless events are missing - node.js

Question

I have a problem with my serverless configuration resulting in lambda functions being deployed without their triggers.
I have a main serverless.yml for my skills, as below:
service: ${file(./${env:DEPLOY_FILE_NAME}):service}
provider:
name: aws
custom:
globalSchedule: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):globalSchedule}
roleName: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):roleName}
profileName: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):profileName}
plugins:
- pluginHandler
runtime: nodejs4.3
cfLogs: true
stage: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):stage}
region: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):region}
memorySize: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):memorySize}
timeout: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):timeout}
keepWarm: false
useApigateway: false
events:
${file(./${env:DEPLOY_FILE_NAME}):events}
package:
exclude:
${file(./${env:DEPLOY_FILE_NAME}):exclude}
functions:
smartHome:
handler: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):handler}
Then, I have two sets of yaml settings files. One for ${skill_type}_${localization} ie customskill_eu.yml and another stage-specific ${skill_type}${localization}{$stage} like smarthome_us_dev.yml etc.
service: alexa-SmartHomeSkillAdapter
exclude:
- app.js
- .idea/**
- .npmignore/**
- .jshintrc
- build/**
- documentation.docx
- dist/**
- event.json
- lambda_function_custom_skill.js
- resources/**
- custom_skill_eu.yml
- custom_skill_us.yml
- smart_home_eu.yml
- smart_home_us.yml
- serverless_settings/**
- tests/**
events:
- s3: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):s3}
- alexaSmartHome: amzn1.ask.skill.d48263be-c7ef-4d61-a773-d6431567e6d6
What is wrong? Please advise.
Thank you.

You need to add events to your functions. Have a read through the serverless documentation for events.
Currently serverless supports lambdas to be invoked by API GateWay, Kinesis, DynamoDB, S3, Schedule, SNS, and Alexa Skill. (read more)
So in this case, adding a required events tag should solve your problem.
...
functions:
smartHome:
handler: ${file(./${env:DEPLOY_FILE_NAME_STAGE}):handler}
events: ${file(./${env:DEPLOY_FILE_NAME}):events}
...
Alternatively, you can always define all resources and their actions using traditional CloudFormation format within serverless resources node.
