Cloudwatch-v2 appender and localstack

[oallauddin]

Is there any way to override the AWS endpoint url 169.254.169.254 when using localstack locally?
We have tried setting environment variables but it appears that it is still trying to log to real AWS instead of localstack.

AWS_ACCESS_KEY_ID=access_key_id
AWS_SECRET_ACCESS_KEY=secret_access_key
AWS_SESSION_TOKEN=session_token
AWS_DEFAULT_REGION=us-east-1
AWS_REGION=us-east-1
AWS_ENDPOINT_URL=http://localstack:4566
AWS_ENDPOINT_URL_CLOUDWATCH_LOGS=http://localstack:4566
