@Marvin What does unable to start work, please ensure you have the necessary dependencies mean? This is a docker pool

The message "unable to start work, please ensure you have the necessary dependencies" typically indicates that there are missing dependencies required for the Prefect worker to function correctly. This is particularly relevant when using a Docker pool, as all necessary dependencies must be included in the Docker image. A related issue was identified with Prefect 2.x where the command

prefect worker start --type ecs --pool batch --install-policy if-not-present

would not work due to dependency conflicts, particularly with the

prefect-aws

package requiring Prefect version

>=3.0.0rc1

. This could lead to the error you're seeing if the Docker image is trying to install incompatible versions of Prefect or its dependencies. To resolve this, you should ensure that your Docker image includes all necessary dependencies at compatible versions. You may need to specify exact versions of Prefect and related packages that are known to work together. For more details, you can refer to this GitHub issue where similar problems were discussed.
