Travis can't download the docker images needed for our builds

The builds made in our project are unable to download the docker images needed to run our tests.

All these builds have the following errors:
docker.errors.ImageNotFound: 404 Client Error: Not Found ("No such image: amazon/dynamodb-local:latest")

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: http+docker://localhost/v1.35/containers/create

Here’s a link to one of those builds,

Thanks in advance.

Does the image exist on DockerHub?

I just checked by using docker pull amazon/dynamodb-local in bash and got the following output.

Using default tag: latest
latest: Pulling from amazon/dynamodb-local
Digest: sha256:cbe14c530c08997a38da04efe3778242f5544e0cdb7e9002fbbc3682f2421c0c
Status: Image is up to date for amazon/dynamodb-local:latest

Looks like image still exists.
