Fn::ForEach Throws "E0001 Error Transforming Template: Duplicate Type while doing transformation" When Used in Resources Section

[jbq2]

cfn-lint 1.18.4

The following snippet shows something similar to what I am attempting to do (hiding exact details of course):

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::LanguageExtensions'
...
Resources:
  Fn::ForEach::Loop:
    - Id
    - - A
      - B
      - C
    - ScheduleGroup${Id}:
      Type: AWS::Scheduler::ScheduleGroup    # <--- complains about this
      Properties:
        Name: !Ref Id
        ...

When I run this through cfn-lint, the linter is complaining that there is a Duplicate Type while doing transformation, specifically highlighting the Type field under ScheduleGroup${Id}. I believe I have followed the examples in AWS docs properly, specifically the 'Replicate Multiple Resources` of this article. I expect that the for each loop expands to the following template after the transformation is performed:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::LanguageExtensions'
...
Resources:
  ScheduleGroupA:
    Type: AWS::Scheduler::ScheduleGroup
    Properties:
      Name: A
      ...
  ScheduleGroupB:
    Type: AWS::Scheduler::ScheduleGroup
    Properties:
      Name: B
      ...
  ScheduleGroupB:
    Type: AWS::Scheduler::ScheduleGroup
    Properties:
      Name: B
      ...

Am I using Fn::ForEach correctly? Or is this an issue with cfn-lint itself? Unfortunately in my situation, I cannot bypass cfn-lint and force the deployment of these resources.

Your indentation is off.

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::LanguageExtensions'
...
Resources:
  Fn::ForEach::Loop:
    - Id
    - - A
      - B
      - C
    - ScheduleGroup${Id}:
        Type: AWS::Scheduler::ScheduleGroup
        Properties:
          Name: !Ref Id
          ...

Hi @kddejong, thank you for noticing. I actually figured it out at work and forgot to close the issue--apologies
