It appears you are encountering a

TimeoutError

during a flow run, but you haven't explicitly set any timeouts. Based on the traceback, the timeout seems to be related to Dask's asynchronous client behavior or to Prefect internals when dealing with suspended or paused flow runs, rather than a flow or task-level timeout set by you. In Prefect, there are default timeouts for suspended runs. Additionally, there are GitHub issues that describe similar problems, which suggest that the error could be related to nested blocks leading to a

TimeoutError

when loaded in a task (issue #8976), or caused by missing state data when the worker's memory overflows (issue #12977). To resolve this, you might need to look into proper configuration for using Dask with Prefect, making sure your task execution does not hit any underlying resource limits, or inspect block-loading patterns that could be causing nested blocks to load incorrectly. For using Dask with Prefect, you can refer to Prefect’s documentation: - Dask integration guide - Concepts of Flows, timeouts, pausing, and suspending For the nested block issue detailed in GitHub issue #8976 and the missing result state problem as in GitHub issue #12977, it's recommended to follow the progress on these issues and apply any proposed solutions or workarounds discussed there. Unfortunately, my capabilities don't include analyzing or debugging application-specific issues in-depth, but I hope pointing you to these resources and discussions helps nudge you in the right direction.
