Not working for second time

[ghorui]

I tried this plugin.. Changes are as follows.
Package.json:
"devDependencies": {
"serverless-plugin-cloudwatch-sumologic": "0.0.10"
}

serverless.yml:
custom:
defaultStage: dev
defaultRegion: us-east-1
AIRID: ''
projectName: "4592_${self:service}"
shipLogs:
# Required
arn: "arn:aws:lambda:us-east-1::function:Cloud***-dev-pushLogs***"
plugins:

• serverless-plugin-cloudwatch-sumologic

When I deployed this project. The Subscription was successful.
but the SID created is with one shortid (append at last). (Not sure from where it is getting populated).

Now I have removed the subscription from the aws console and re-deploy the function again.
First: when I removed the subscription manually, the corresponding entry in Function Policy file did not reverted back.
Second: When I re-deploy the code, subscription did not take place.
Third: I tried re-deploying after flushing the function policy file with "aws lambda remove-permission" command. In this case also the subscription did not take place.
