Your issue with Prefect 3.1.0, where your flow seems to be stuck and isn't generating tasks or updating logs, might be related to a few potential causes. Here are some steps and considerations that might help you resolve the issue:
1.
Check Network: If you are using Prefect Cloud, ensure that your network connection is stable and that you are logged into the correct Prefect Cloud account. You can confirm by logging into
Prefect Cloud 3 (source:
troubleshooting cloud issues).
2.
Flow State Management: Occasionally, flows may get stuck in a "Pending" state. Ensure your flow is scheduled and running as expected. You may try canceling and rerunning the flow if it remains unresponsive (source:
interacting with the Prefect API).
3.
Infinite Generators: If your tasks involve generators, ensure they are not infinite or excessively large, as this can cause blocking or unexpected behavior (source:
writing tasks in Prefect).
If these steps do not resolve the issue, you may want to further investigate by looking at the logs directly on the server, checking for any network errors, or reviewing the deployment configuration. Using Prefect's debugging features or increasing the verbosity of your logs might also provide more insights into what is causing the loop. If you encounter a specific error message or behavior, providing more details can help narrow down the issue further.
