Unknown Tag !Join

[brettstack]

I have added "!Join" to config along with others. This is the only one that gives an error. I assume it's to do with the way it's being used? i.e. it expects an array instead of a string like !Ref

ProviderName: !Join
  - ''
  - - cognito-idp.
  - !Ref 'AWS::Region'

When trying that code in yaml-js I get could not determine a constructor for the tag !Join, so it doesn't look like it supports that construct in the first place. Is that valid YAML or an expansion of some sort?

This is an AWS CloudFormation expansion

This provider is just a wrapper around yaml-js, so if it doesn't understand that, then it won't be understood in here either unfortunately.

Hi I've added the custom tags but somehow i get this error;
AvailabilityZone: !Select [ 0, !GetAZs ] -> unknown tag !<!GetAZs>

just using pure linter-js-yaml package for linting yaml.

Also receiving an unknown tag error on !GetAZs. I have entered it in the custom tags both as !GetAZs and !

I have same issue with !secret, all other custom tags works ..

As explained above, if yaml-js doesn't understand these custom tags, this provider won't either. Are you saying that you have configured yaml-js in a manner that when you run it it doesn't flag those as issues, but when running it here in Atom it does?
