SNS event configuration ignored

aws
lambda
#1

I tried to write two functions, which should subscribe to different sns topics,

My config looks as following:

VehicleShared:
    handler: src/functions/sns/VehicleShared.handler
    events:
        - sns:
              arn:
                  Fn::Join:
                      - ""
                      - - "arn:aws:sns:"
                        - Ref: "AWS::Region"
                        - ":"
                        - Ref: "AWS::AccountId"
                        - ":vehicle-shared-dev"
              topicName: vehicle-shared-dev
VehicleUnshared:
    handler: src/functions/sns/VehicleUnshared.handler
    event:
        - sns:
              arn:
                  Fn::Join:
                      - ""
                      - - "arn:aws:sns:"
                        - Ref: "AWS::Region"
                        - ":"
                        - Ref: "AWS::AccountId"
                        - ":vehicle-unshared-dev"
              topicName: vehicle-unshared-dev

After deploying the function VehicleShared is subscribed to the vehicle-shared-dev event, as expected.
But the stange thing is, that the subscription for the VehicleUnshared Function was not created.

Has anyone experienced similar problems?

In the YAML you have pasted the function VehicleUnshared, event is missing the s on the end.

VehicleUnshared:
    handler: src/functions/sns/VehicleUnshared.handler
    events:
