[cloudformation-include] Resource used in GetAtt not found when using single quotes in template

[fongie]

When the imported template uses single quotes like !GetAtt 'MYID.Arn' cdk synth fails with Resource used in GetAtt expression with logical ID: ''MYID' not found (note the double single quotes in the error message)

Reproduction Steps

In my case:

NATIP:
        DependsOn: VPCGatewayAttachment
        Type: 'AWS::EC2::EIP'
        Properties:
            Domain: vpc

NATGateway:
        Type: 'AWS::EC2::NatGateway'
        Properties:
            AllocationId: !GetAtt 'NATIP.AllocationId'
            SubnetId: !Ref Subnet1

What did you expect to happen?

I was trying to cdk synth having imported my (already working in and deployed) yaml template using this code in a new stack

    const templateFile = path.join(__dirname, '../templates/template.yml');
    const include = new CfnInclude(this, 'Template', {
      templateFile
    });

What actually happened?

Resource used in GetAtt expression with logical ID: ''NATIP' not found
Subprocess exited with error 1

Environment

• CLI Version : 1.62.0 (build 8c2d7fc)
• Framework Version: 1.62.0
• Node.js Version: v14.3.0
• OS : mac Mojave 10.14.6
• Language (Version): Typescript ~4.0.2

Other

Judging from the error message it seems an extra ' is making its way into the resource name somehow.
