Cfn-python-lint: APIGW Authoriser definition not supported

[xiaket]

cfn-lint version: cfn-lint 0.16.0

Hi, there!

Thanks for this great tool! It looks really promising! :)

I think this is yet another SAM issue. The following piece of template works in Cloudformation, but cfn-lint think otherwise :P

  API:

This is an error we are getting back from samtranslator

I believe this is the issue that corresponds to the problem you are having.

Cheers mate, thank you for pointing me to the right direction! Please feel free to close this.

I'm going to leave this open for a little bit. We have seen a spike in SAM issues in the last week or two. Since the template deploys I want to see if they can fix this or if we will have to "fix" it. Kind of like what we are talking about for #700

[kddejong]

We should have a work around for this in the next release as a result of #778

[kddejong]

Released.
