Filter Error Issue

Getting the following error on my filter node: Filter Failed! No value output for ‘output1’ as input ‘input1’ was filtered out.

What does this mean?

Hey @user10! If you’re reporting an issue with a flow or an error in a run, please include the run link and make sure it’s shareable so we can take a look.

  1. Find your run link on the history page. Format: https://www.gumloop.com/pipeline?run_id={your_run_id}&workbook_id={workbook_id}

  2. Make it shareable by clicking “Share” → ‘Anyone with the link can view’ in the top-left corner of the flow screen.

  3. Provide details about the issue—more context helps us troubleshoot faster.

Hey @user10 - This means no input met the condition that you set hence there’s no valid output available. Looking at your workflow you should probably remove the quotes around the conditional value – the filter node is case sensitive and does exact match on the string

Question instead of → 'Question'

Let me know if that works.

Thanks Wasay. I tried removing the quotes. Still didn’t work (https://www.gumloop.com/pipeline?workbook_id=7tbBfW5GK9bdgfbUt5Ceid&run_id=fHxaT6DPisuGRxFUpSoBrZ). For context, here is a sample output from the previous step which is being fed into the fiter:

It didn’t work because none of the inputs in the Filter by list met the condition. You can verify this by viewing the inputs/outputs of the filter node from the run log.

Instead of using the combine text node, I believe you want to pass the Category output into the Filter by and the Slack Message into the filter Input

This is what I tried initially. What I am trying to achieve is: read slack messages from a channel. Use AI categorizer to identify if it is a question. If yes, then send it to a dedicated slack channel. When I filtered on category, and plugged in the slack messages to the filtrer node input, it sent all slack messages to the slack channel irresepctive of wheter it was a question or not.

Wrt non of the conditions met the criteria, I pasted the output of the combined text node as a screenshot earlier. If you see, there is clearly text which contains ‘Question’. This should have met the filter condition?

In the run link you shared above though there are still quotation marks

Try removing them, save the workflow and run again.
