Describe the bug

I am trying to add a condition where it compare if a CommaDelimitedList parameters had two elements.

Conditions:  
   TwoVpcConfig: !Equals [ Fn::Length: !Ref VpcCIDRs, 2 ]

and I get the following error:

[cfn-lint] E1030: {'Fn::Length': {'Ref': 'VpcCIDRs'}} is not of type 'string'

However this errors started few days ago with an update of cfn-lint.

AWS Documentation states that Equals should accept any type of value and CommaDelimitedList is actually and array so Fn::Equals and Fn::Length should not complain.

If I ignore E1030 from cfn-lint the template deploys correctly with no issue.

Expected behavior

It should not complain
