Cloudformation throws UserPoolTestDomain ROLLBACK_FAILED

[Pelirrojo]

Hi there,
Thanks for the amazing Custom Resources!

I've been playing with it but I can't deploy:

Cloudformation event error:

13 Nov 2018 16:59:53 | UserPoolTestDomain | CREATE_FAILED | Invalid Response object: 'null' is not a valid ResponseStatus
-- | -- | -- | --

CloudWatch Errors:

I've try to deploy in two cloudformation templates (one for lambdas & permission and another for demo resources) but the same problem there.

Do you have experiment the same problem?

Thanks,
Manuel

Yup. I am having the same issue. Where you able to resolve it?

[Pelirrojo]

No, finally we use an cli command scripted to do the trick.

I figured it out. You have to specify a unique domain:

UserPoolTestDomain:
Type: 'Custom::CognitoUserPoolDomain
Properties:
ServiceToken: !GetAtt CloudFormationCognitoUserPoolDomain.Arn
UserPoolId: !Ref UserPoolTest
Domain: <unique domain that hasn't already been taken> <--#Here
Thanks
:)
