Getting a "Bad indendation in FLOWMAP" error about yaml-pp-p5

[perlpunk]

That is invalid YAML, but I'm aware that several parsers accept it.
Even the closing } is below the Item entry, and per definition any content below a certain key must be indented with at least one space.

Wow! One space fixed it all :)

It's kind of difficult to distinguish between invalid-but-accepted YAML and not-supported-yet-in-yaml-pp YAML. Sorry for overreporting.

Is there any way of getting YAML::PP to parse it via something in: https://metacpan.org/source/JLMARTIN/Cfn-0.13/lib/Cfn/YAML/Schema.pm

Would you accept a patch that enables the activation of such a "feature"?

That has nothing to do with the Schema.
This would have to be implemented in the Lexer, and you can have a look at it if you want.
