Run ends with “Completed Successfully with No Output” — Run-Function block (write_to_google_sheet) never executes

What happens (detailed):

  • Every time I click Run in Tab (or use the public link) the agent finishes with the banner “Completed Successfully with No Output.”
  • The debugger timeline shows the blocks up through Generate Text, but the downstream Run-Function block write_to_google_sheet never fires (no console logs, no status/body).
  • Because that block doesn’t execute, no POST request reaches my Google Apps Script Web-App, so no rows are written to the Google Sheet.
  • // @standalone is in place, Test Data is set, Transition Type = Dynamic, yet the single-function Test runner also refuses to start.
  • Curling the Web-App URL directly returns “Success” and appends rows, so the endpoint itself is healthy.

Intended behavior:
write_to_google_sheet should receive steps.generate_text.result, POST the JSON array to my Web-App URL, and append new rows to the BozLeads tab of the sheet.

Attachments:

  • Screenshot #1 – success banner with “No Output.”
  • Screenshot #2 – debugger timeline (note missing write_to_google_sheet step).
  • Run-log JSON – exported from the latest run.
  • Apps-Script execution log – shows no requests arrive during the MindStudio run, but succeeds when hit via curl.

Environment:

  • Workspace plan: Pro
  • Browser: Chrome v115 on macOS 14.5
  • Agent duplicated into a fresh project / incognito window — same result.

Let me know if you need any additional logs or a Loom; happy to provide. Thank you!

It looks like you’re using a Custom Function? We don’t support the actual code within a Custom Function - it’s on the developer to make sure it works.

Have you tried our native Google Sheet block instead of a custom function?

I’m new to Mindstudio. I didn’t see a Google block. Is there one?

Hi @slaflora,

When adding a block, scroll down to the Google section to add an Update Google Sheet or similar block:
