Is there a way using the UI logs tab to open the task that caused an error ?

Hi @Marwan Sarieddine - if you mouse over the log, a button should come up that will take you to the task run in question 🙂

Ah - yep just saw the

to task run

button Thank you!

No problem! We'll look to make that a little clearer in the future 🙂

@nicholas as a follow-up, is there a way using the task run schematic viewer to see the inputs of the task ? The usecase is I have a mapped task, where one child failed and the other passed, I’d like to know which inputs caused the one that failed

@Marwan Sarieddine unfortunately that's not possible because Prefect doesn't see the data that's passed between tasks

ah I see - what about in prefect core server - i.e. not prefect cloud ?

That's correct @Marwan Sarieddine 🙂

true - but that’s what I had done - I ran the flow on a small subset of the data locally and the flow ran successfully. Then running the flow on the entire data - caused a failed child task - which I am trying to figure out the inputs that caused the failure so I can copy them remotely and try it out …

Got it - as long as the data can be serialized, you can always send it to your Server logs via a logger (

<http://self.logger.info|self.logger.info>

etc.); since this will send data to Cloud/Server, you'll want to use it accordingly. You can read more about loggers here: https://docs.prefect.io/core/concepts/logging.html#prefect-loggers

thanks - thats a reasonable solution

You can navigate to the logs of a specific task or task run to get the logs for just that task, there isn't a way to filter them from the flow logs page.

I see - thanks
