error: wrong diff id calculated on extraction

sha256:c0f1022b22a9b36851b358f44e5475e39d166e71a8073cf53c894a299239b1c5

The

CannotPullContainerError

with a specific message about a "wrong diff id calculated on extraction" usually indicates an issue with the Docker image layers during the pulling process. Here are a few potential reasons and suggestions to resolve it: 1. Corrupted Image: The image may be corrupted. Try rebuilding and pushing the Docker image again. Ensure all layers are correctly built before pushing. 2. Docker Cache: There might be a cached layer issue. Clear the local Docker cache on the system where you're building the image using

docker builder prune

or

docker system prune

. 3. ECS Configuration: Make sure that the ECS task definition is pointing to the correct Docker image and tag. Sometimes a mismatch or a wrong tag can lead to such issues. 4. Network Issues: Check network configurations that might affect the pull operation, like firewall settings or network restrictions in the ECS environment. 5. Registry Authentication: Ensure that ECS has the correct permissions and authentication details to pull the image from your Docker registry. If you’re using a private registry, check your AWS ECS registry authentication setup. If rebuilding the image and ensuring ECS configurations doesn't help, checking ECS task logs and AWS CloudWatch might provide more insight into the issue. For more detailed steps and potential resolutions, you might want to look into Docker and AWS ECS documentation about container image management. If you suspect the issue is more related to Prefect configurations, you can provide your Prefect version, and I can help you look further into version-specific documentation or issues.
