@Marvin How do I get prefect flow cloud url in python code?

Oh dear, it seems the universe is conspiring against us. Let's give it another go. { "mode": "plugins", "objective": "Find information on configuring task runners at the task level in Prefect 2", "tasks": [ { "id": 9, "name": "Find information on task runners configuration", "is_complete": false, "results": "" } ], "plugins": [ { "id": 9, "name": "chroma_search", "inputs": { "query": "configure task runners for individual tasks in Prefect 2" }, "tasks": [9] } ] }

@Marvin can you explain task runners in prefect 2?

@Marvin Can I use the REST API to pull a running flow log messages?

@Marvin can a flow log also be written to CloudWatch?

@Marvin How do I return a Failed state from a flow in Prefect 2?

@Marvin Can I set PREFECT_HOME to a shared drive location?

Ah, the answer has revealed itself. In the mystical land of Windows, the SQLite database for Prefect 2 resides at

~/.prefect/prefect.db

. This path is a hidden treasure, waiting to be discovered by adventurers like yourself. Good luck on your journey through the world of Prefect, and may the odds be ever in your favor. source

@Marvin where does the sqlite database live in Windows for Prefect 2?

Did Marvin just… time travel

@Marvin What can I do if my kubernetes work queue goes unhealthy?

@Marvin How do I trigger a Prefect Cloud flow from Python?

@Marvin can you explain how to hit the Prefect 2 API with httpx?

@Marvin Okay, we know you know Python. But can you tell me how to hit the Prefect 2 REST API from Micro Focus COBOL running on the JVM? It's okay to import Java libraries, but the code needs to be in COBOL. Asking for a friend.

@Marvin how can I omit the env part in the Docker Container infrastructure in the UI ?

@Marvin What would be the best way to access variables from within a Flow in a State Handler? I'm making a Flow that runs Jupyter notebooks, and on failure I want to post a link to the failed notebook file to slack. There's a task earlier in the flow that generates the filepath.

@Marvin I have two questions. Part 1: I have scheduled multiple flow runs for the same time (12pm). My flow runs are crashing with the following error: prefect.exceptions.PrefectHTTPStatusError: Server error '500 Internal Server Error' for url 'http://ephemeral-prefect/api/block_documents/'. Why is this happening? Part 2: Demonstrate how I could implement SequentialTaskRunner to run multiple flows at the same time (example: 12pm) daily without crashing.

@Marvin What's the Prefect 2 equivalent of

prefect.client.Secret

?

@Marvin how do I create my own Custom Pickle Serializer?

@Marvin in prefect cloud my default work pool always shows the status "unhealthy". It has been like this since I created the account, why is this?

@Marvin On the homepage, it states you can “Use for or while loops to create infinitely-long flow runs, no schedule required”. Can you give an example of a continuous workflow?

@Marvin how do I iterate through all the tasks associated with a flow in Prefect 2?

@Marvin what is a work pool?

@Marvin is it possible to run subflows in a separate instance as the main flow?

@Marvin Is there a way to delete or stop pending flow runs from Python?

Hey @Marvin ! I have an issue regarding to GCP. When I trigger docker image in GCP UI as a cloud run job it is successful however when I try to use prefect and trigger a cloud run I can see the job in both cloud run and prefect ui. But it crashes all the time. Log is : File "/usr/local/lib/python3.11/site-packages/prefect/client/orchestration.py", line 1634, in read_flow_run response = await self._client.get(f"/flow_runs/{flow_run_id}") I have checked everywhere but couldn't find a solution. I can reach the flow id and name however I dont know what to do with it.

hey @Marvin I have a task that makes a request to an API. That API has a concurrency limit such that I can only have 5 active requests out with it at any given point in time. Can I set a task-level concurrency limit using prefect such that I don't ever have to worry about bypassing the concurrency limit with this third party API provider?

also @Marvin , what's the most idiomatic way to establish dependencies between async tasks?

I couldn't find any specific issues directly related to running

prefect server start

after

prefect server database reset

. However, I found some issues that might be related to database reset or Prefect server start: 1. Flow runs duplicated when DST ends (v2): This issue is about duplicate flow runs being created when daylight saving time ends. It might not be directly related to your problem, but it's worth checking if your issue is related to daylight saving time changes. 2. Unable to create notifications after database reset: This issue is about the Prefect UI not working correctly after a database reset. It might not be directly related to your problem, but it shows that database reset can cause some unexpected behavior. 3. Prefect 2.6 uses non-implemented feature in pydantic. Related to return value: This issue is about an error being raised after upgrading to Prefect 2.6 and resetting the database. It might not be directly related to your problem, but it shows that database reset and Prefect version upgrades can cause some issues. To better assist you, please provide the error message you encountered when running

prefect server start

. This will help me understand the issue and find a solution for you.

@Marvin would you kindly write a Seinfeld standup routine where he explains how to set up a Prefect worker? I learn best in comedy form, so I'd sincerely appreciate if you can accommodate my request.
