Running pull_from_s3 step...

I get

prefect.*exceptions*.ScriptError: Script at '*' encountered an *exception*: FileNotFoundError(2, 'No such file or directory')

but the file definitely exists. What could be the cause?

The

FileNotFoundError(2, 'No such file or directory')

during the

pull_from_s3

step could be caused by several factors even if the file definitely exists. Here are a few possibilities and steps to investigate: 1. File Path Issues: Ensure the file path specified in the pull request is correct. Double-check for any typos or incorrect path specifications in the configuration. 2. Permissions: Verify that the IAM role or AWS credentials configured have the proper permissions to access the S3 bucket and the specific file. 3. File Consistency: Make sure the file wasn't deleted or moved in the S3 bucket after initiating the request. 4. Network and Region Settings: Check if there are any network issues, like S3 bucket region mismatches, that could prevent access to the file. 5. Use the Latest Method: The

pull_project_from_s3

method is deprecated. Make sure you are using

pull_from_s3

as per the latest Prefect AWS integration documentation here. You can further debug by printing the paths and logging the detailed error message to pinpoint the issue. You might also want to confirm the AWS SDK version you're using is compatible with the Prefect integration. If you need to dive deeper into the Prefect logs or configuration, feel free to ask for additional specifics.

Unfortunately printing the paths is impossible since this is an ecs push work pool. The container is failed as it starts since it cannot find the file.

In the context of retrieving a flow from S3 for an ECS push work pool in Prefect, the relevant permissions and roles to check would be: ECS Task Role: This role is typically used by the actual ECS tasks running your code. The task role needs permissions to access the S3 bucket where your flow is stored. Here is a summary: - ECS Task Role: Ensure this role has the necessary permissions to access the S3 bucket (e.g.,

s3:GetObject

). There weren’t specific details about the roles in the search results, but configuring the ECS Task Role should be your primary focus for S3 access within an ECS push work pool. For more information, refer to Prefect AWS Integration Documentation and AWS ECS Task Roles. If you need further detailed steps or encounter specific issues, please provide more details on your current setup or error logs.
