Deploy fails with "pathmapping - Invalid stage identifier specified"

I can't seem to add serverless-api-stage to a project which contains the serverless-domain-manager plugin. Deployment fails with the error:

...
Serverless: Uploading CloudFormation file to S3...
Serverless: Uploading artifacts...
Serverless: Uploading service .zip file to S3 (15.76 MB)...
Serverless: Validating template...

I've narrowed it down to an interaction between the two plugins.

Here's a repo which demonstrates the issue:

Hi @leftclickben - There might be a solution in this comment:
serverless/serverless#4029 (comment)

I'm not sure whether the change is best made here or in https://github.com/amplify-education/serverless-domain-manager

FWIW, I'm using serverless-api-stage mainly to get APIGateway logging working. I'm using serverless-domain-manager to automate deployment of stage-specific subdomains.

Just to add my findings here, I was TRYING to use both of these plugins together as well. But after testing different combos and parameters, it seems as though its this plugin thats causing the issues. When i ran domain-manager by itself without this plugin being registered in serverless.yml, everything ran fine. But when I disabled domain manager and enabled this plugin, it failed with above message. I created a APIGW deployment and BasePathMapping with custom resources and set the basepathmapping to DependsOn the deployment resource. However, i noticed this plugin running intermingled with the CREATE_IN_PROGRESS and CREATE_COMPLETE for the custom resources being created which ended up throwing the same error since stage was not complete yet.

@aneilbaboo @leftclickben I have solved the issue on this PR I can now use domain manager and api key and usage plans all together. #25
