Error response from daemon: (NotImplemented) image push is not implemented

Hi, I’m getting an error while trying to push an app to an aws cluster with coldbrew

Expected behavior

Image should be pushed successfully to cluster created by coldbrew

Actual behavior

Getting the following error:
Error response from daemon: (NotImplemented) image push is not implemented (ff16341b-d164-445e-9b80-3b32a1b93dea)

Additional Information

Following the tutorial that can be found at

###Repro steps
I was able to repro the problem by using docker push directly:
docker push AWS_ACCOUNT_ID.dkr.ecr.ca-central-1.amazonaws.com/ib-ecs2:latest

Someone has an idea of what might cause the error? Or at least have an understanding of at what level this occurs?

Thank you,

Francis Renaud
