Warning: use same module and package versions!

Use version parameter to pin to a specific version, or to specify a version constraint when pulling from Terraform Module Registry (source = baikonur-oss/lambda-es-cleaner/aws). For more information, refer to Module Versions section of Terraform Modules documentation.

Make sure to use ?ref= version pinning in module source URI when pulling from GitHub. Pulling from GitHub is especially useful for development, as you can pin to a specific branch, tag or commit hash. Example: source = github.com/baikonur-oss/terraform-aws-lambda-es-cleaner?ref=v1.0.0

For more information on module version pinning, see Selecting a Revision section of Terraform Modules documentation.
