New RunLLM response generated: >>>*# Question* Hi All, I am trying to upload a JOSN file as a FlyteFile to remote S3, but getting error -

TypeError: Object of type FlyteFile is not JSON serializable

I am getting the same error even if I create a JSON file locally first and then pass S3 URL as remote_path. Any help would be appreciated. Thank you # Answer The error you're encountering suggests that the

FlyteFile

object is not being correctly serialized to JSON. This is likely because

FlyteFile

is a specialized type in Flyte that handles file paths and URIs, but it doesn't directly serialize to JSON. To resolve this, you should ensure that the

FlyteFile

is being used correctly within a Flyte task or workflow. When you want to upload a file to S3, you should use the

FlyteFile

type to handle the file path and let Flyte manage the upload process. Here's a basic example of how you can use

FlyteFile

to upload a file:

from flytekit import task, workflow
from flytekit.types.file import FlyteFile

@task
def upload_file(local_path: str) -> FlyteFile:
    # Create a FlyteFile object with the local path
    file = FlyteFile(local_path)
    # Flyte will handle the upload to the remote location
    return file

@workflow
def my_workflow(local_path: str) -> FlyteFile:
    return upload_file(local_path=local_path)

Make sure that the local path is correctly specified and that Flyte is configured to use S3 as the backend storage. If you continue to face issues, please provide more details about how you're using the

FlyteFile

and any relevant code snippets. Would you like more details on this process or any other aspect of Flyte?
