Required Capabilities Cloudformation Template

I am getting an exception when Deploying a cloud formation template regarding Requires capabilities : [CAPABILITY_IAM].

I have done some research and found out that when using IAM resources in the template we have to explicitly tell AWS that we are aware of IAM resources in the template.

I have done that. Below is my command

$ ./update.sh ScalableAppCore AppServers.yml AppParameterCore.json --capabilities CAPABILITY_IAM

$ ./update.sh ScalableAppCore AppServers.yml AppParameterCore.json --capabilities CAPABILITY_IAM CAPABILITY_NAMED_IAM

$ ./create.sh ScalableAppCore AppServers.yml AppParameterCore.json --capabilities CAPABILITY_IAM CAPABILITY_NAMED_IAM CAPABILITY_AUTO_EXPAND

Tried all 3 commands but still, the output shows:
An error occurred (InsufficientCapabilitiesException) when calling the UpdateStack operation: Requires capabilities : [CAPABILITY_IAM]

Here is the actual code :

This is the Role I have created for S3

IamS3Role:
    Type: AWS::IAM::Role
    Properties:
      ManagedPolicyArns:
        - "arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess"
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:
          - Effect: Allow
            Principal:
              Service:
                - ec2.amazonaws.com
            Action:
              - 'sts:AssumeRole'
      Path: /

Instance Profile attachment

ProfileWithRolesForApp:
    Type: AWS::IAM::InstanceProfile
    Properties:
      Path: "/"
      Roles:
        - !Ref IamS3Role
  

Please let me know where I am wrong . Thanks in advance
