  2. On the Select Template page, choose Next.

  3. On the Specify Details page, set the following options:

    1. Choose the Lambda runtime, depending on what language you want to use in your Lambda function. These Amazon CloudFormation templates currently support the following languages:

      • Python 3.9 (maps to python39 in the Amazon S3 URL)

      • NodeJS 18 (maps to nodejs18x in the Amazon S3 URL)

      • Ruby 2.5 (maps to ruby25 in the Amazon S3 URL)

    2. Provide the appropriate Neptune cluster endpoint and port number.

    3. Provide the appropriate Neptune security group.

    4. Provide the appropriate Neptune subnet parameters.

  4. Choose Next.

  5. On the Options page, choose Next.

  6. On the Review page, select the first check box to acknowledge that Amazon CloudFormation will create IAM resources.

    Then choose Create.

If you need to make your own changes to the Lambda runtime, you can download a generic one from an Amazon S3 location in your Region:
