"Set column values" workflow step — Row/table dropdown won't open (Webhook-triggered workflow)

I’m building a workflow with a Webhook trigger → “Set column values” action. The “Row” field on the “Set column values” step doesn’t respond to clicks at all — the dropdown never opens.

I’ve tried the following, with no change:

  • Hard refresh and resetting browser zoom to 100%
  • Maximizing/resizing the browser window
  • Deleting and recreating the “Set column values” step from scratch
  • Testing in Incognito mode with all extensions disabled
  • Creating a brand new test table to rule out an issue with an existing table’s schema — same result, dropdown still doesn’t open

The Webhook trigger step itself works fine and correctly shows its URL, bearer token, and test data — the issue is isolated specifically to the “Row” field on the step immediately after it.

Has anyone else run into this, or know of a workaround?

Thanks!

Do you actually have a row selected via a previous workflow step?
A webhook triggered workflow is by default not attached to any table or row, so if you want to operate on a specific table/row then you first have to provide that context.

What needs to be done depends on what you are expecting to be passed via the webhook.
Let’s imagine (for example) that you’re expecting an update to a specific Users record, and you’re expecting the affected Users RowID to be passed via the webhook.

  • What you would do first is extract the RowID value from the webhook data (and yes, a Query JSON step would work for this)
  • You would then directly target the affected Users row. There are a few ways to do this. You could use a Single Query, filtering by RowID, or you could loop over the whole table, again filtering by RowID. The first approach is cleaner, but either would work.
  • Once you’ve done that, you can then change values in that row via Set Column values (if there are new values in the webhook data you would need to extract those first).
