I keep on getting

`An error occurred: HelloWorldLambdaFunction - hello-world already exists.`

How can I insure that the serverless deploy will overwrite existing lambda functions even if there is no change? I tried adding the --force flag to my serverless deploy command but no luck.

I would like to know if anyone was able to figure this out as well
