InvalidParameterValueException: SubnetIds and SecurityIds must coexist or be both empty list.

In description of lambda I'm describing parameter like this
```
- name: default deploy
uses: appleboy/lambda-action@v0.1.9
with:
aws_access_key_id: ${{ secrets.AWS_ACCESS_KEY_ID }}
aws_secret_access_key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
function_name: func-1
source: functions/func-1/main
memory_size: 128
timeout: 300
handler: main
role: "arn:aws:iam::foo:role/func-1-role"
runtime: go1.x
subnets: "subnet-123456,subnet-123465,subnet-423156"
securitygroups: "sg-asdqwf324234"
environment: ENVIRONMENT=foo
```
And I keep receiving error
`InvalidParameterValueException InvalidParameterValueException: SubnetIds and SecurityIds must coexist or be both empty list.`
I've tried to find example how to describe the subnets and SG but unfortunately didn't find any.

How to properly provide list of subnets and SG's here?
