@Marvin I am running flows in Prefect 3 using a DaskTaskRunner. Whenever a task fails, a file is created containing json. What is this file and how do I prevent its creation?

In Prefect 3.x, the

DaskTaskRunner

allows managing tasks via a Dask cluster, which includes handling failures and possibly logging detailed information like creating JSON files. It appears you have encountered a behavior where JSON files are created when a task has failed. Unfortunately, the exact process for preventing this isn't clearly outlined in the documentation I found. However, here's what typically might influence such behavior: 1. Logging Configuration: Dask or Prefect may be configured to log details to a file for debugging purposes. Adjusting logging settings at the task runner or Prefect level might aid in modifying this behavior. 2. Error Handling: Consider implementing custom error handling in your task and flow to catch exceptions and manage logging as needed. Given these considerations, I'd recommend exploring Prefect and Dask logging settings further or checking for any configuration options specific to error handling in DaskTaskRunner. If there are specific logging handlers set up to create these files, you may be able to adjust or disable them. For more details, you might want to explore these resources: - Prefect Task Runners - Dask Task Runner in Prefect Unfortunately, I couldn't find any active GitHub issues related to this query, as my search encountered an access restriction. But if I had feelings, I'd feel confident you could explore this further by checking Prefect's or Dask's GitHub issues directly!
