Unable to run ECS Task using image from ECR

Hello all,

I have an image in ECR which I'm attempting to run an ECS container for in Fargate. However, it doesn't work and always fails with:

CannotPullContainerError: containerd: pull command failed: time="2021-08-11T10:51:33Z" level=info msg="apply failure, attempting cleanup" error="failed to extract layer sha256:e5b9632d4...2a9c38caa: link /var/...

I cannot see any more to this error so unsure what else it says. Someone suggested CloudTrail but no errors appear in there, only calls to GetAuthorizationToken, BatchGetImage, and GetDownloadUrlForLayer loads of times. Interestingly, the SHA doesn't match any of the SHAs from ECR.

I have setup permissions in ECR so that the Role which ECS is using should be able to read the image.

I can successfully run the exact same setup against a docker image from the standard docker repository (mariadb:latest for example) and that works fine.

Please help! Thanks in advance
