Hello, I’m reposting an issue i’m having as I have not been able to resolve. I have created a deployment using an ECStask block. The ECStask block is configured to run an existing task definition. When I try to run the deployment I get the following error: Submission failed. KeyError: "No class found for dispatch key 'ecs-task' in registry for type 'Block'." This error shows up under details of the flow run but there are no other logs. I already tried registering the block again. cc: @Taylor Curran

It sounds like

prefect-aws

isn’t installed on your agent.

I followed these instructions to set up the agent https://github.com/PrefectHQ/prefect-recipes/tree/main/devops/infrastructure-as-code/aws/cli-prefect2-ecs-agent. How do I validate prefect-aws is installed and install?

If you add an environment variable like https://github.com/PrefectHQ/prefect-recipes/blob/main/devops/infrastructure-as-code/aws/cli-prefect2-ecs-agent/prefect-agent-td.json#L31-L34

Thanks!

Hi @Zanie does this method still work? my definition contains:

{
    "taskDefinitionArn": "arn:aws:ecs:us-east-1:<My account ID>:task-definition/cyflows:18",
    "containerDefinitions": [
        {
            "name": "cyflows",
            "image": "prefecthq/prefect:2.7.12-python3.9",
            "cpu": 0,
            "links": [],
            "portMappings": [],
            "essential": true,
            "entryPoint": [
                "bash",
                "-c"
            ],
            "command": [
                "prefect agent start -q cyflows"
            ],
            "environment": [
                {
                    "name": "EXTRA_PIP_PACKAGES",
                    "value": "prefect-aws"
                },
                ...

but it seems the agent does not have prefect-aws installed, outputting the same error.
