Complete example fails plan with two service integrations

[jademackay]

Description

Terraform plan on a pared down version of the complete example (terraform-aws-step-functions/examples/complete/) returns Error: Inconsistent conditional result types

Reproduction

cd terraform-aws-step-functions/examples/complete
terraform init

Edit content of main.tf as follows (commented such that only lambda and dynamodb remain):

...
  service_integrations = {

    dynamodb = {
      dynamodb = ["arn:aws:dynamodb:eu-west-1:052212379155:table/Test"]
    }

    # athena_StartQueryExecution_Sync = {
    #   athena        = ["arn:aws:athena:eu-west-1:123456789012:something1:test1"]
    #   glue          = ["arn:aws:glue:eu-west-1:123456789012:something2:test1"]
    #   s3            = true # options: true (use default value from `aws_service_policies`) or provide a list of ARNs
    #   lakeformation = ["arn:aws:lakeformation:eu-west-1:123456789012:something3:test1"]
    # }

    lambda = {
      lambda = ["arn:aws:lambda:eu-west-1:123456789012:function:test1", "arn:aws:lambda:eu-west-1:123456789012:function:test2"]
    }

    # xray = {
    #   xray = true
    # }

    #    # NB: This will "Deny" everything (including logging)!
    #    no_tasks = {
    #      deny_all = true
    #    }
  }
...

Resulting error:
