Error Message

Function “xxxxxx” doesn’t exist in this Service


Serverless Framework is complaining that it cannot find a Lambda function with the specified name.


Here are a few things to check if you are running into this issue:

  1. Double check the spelling and case. Ensure the name of the function you are trying to invoke matches the one defined in the functions section of your serverless.yml. For example, if your serverless.yml looks like:

    service: hello-world
        handler: get.main

    The correct function name when trying to invoke is serverless invoke local -f get, not serverless invoke local -f hello-world-dev-get.

  2. Alternatively, if you are doing a remote invoke (not serverless invoke local), make sure the service has been successfully deployed. You can check if the service has been deployed by running serverless info. And the function you are trying to invoke should be listed under functions.

    For example, you might see something like this:

    Service Information
    service: hello-world
    stage: dev
    region: us-east-1
    stack: hello-world-dev
    resources: 11
    api keys:
      GET -
      get: hello-world-dev-get

    This means that you can now invoke the function using serverless invoke -f get.
