The final policy size is bigger than the limit

[Kay_Khan]

I use functionbeat to ship aws lambda function logs to elasticsearch. I added a new log group today and when i attempt to update functionbeat i get the following error:

The final policy size (20576) is bigger than the limit (20480). (Service: AWSLambdaInternal; Status Code: 400; Error Code: PolicyLengthExceededException; Request ID: 4815dab8-f579-439b-977a-dd71810d168a; Proxy: null)

The policy is something functionbeat is updating automatically i assume as that is not something i am handling in my configuration

functionbeat: 8.2.2
