Al Workflow Error After Updating To 2.16.0

Bug Reports

I recently updated BoltAI to 2.16.0 and since then my AI Workflows have started throwing an error.

Here is a screen recording of the issue: https://drive.google.com/file/d/1CD_1v13nCLy969WKpOmAnYq1FCVf2-vj/view

As you can see in the video, I trigger the workflow using a keyboard shortcut. After the text processes, a pop-up shows the following error message: "Workflow Failed: The model returned an empty response."

You can check the configuration details for this specific workflow here: https://i.ibb.co/y3FB66h/Bolt-AI-Workflow.jpg

Is this a known bug with the 2.16.0 update, or is this an isolated issue on my end?

    Sorry for the issue. It’s likely a bug from BoltAI with my recent newer inference engine for Workflow. It’s supposed to be faster but looks like the network stack doesn’t work reliably. Does it happens all the time or sporadically?

    Can you go to Settings > Developer > Feature Flag and enable the Legacy Inference Engine. Then try again and let me know if it works better.

      Thanks for the quick reply, @Daniel Nguyen.

      I ran a few more tests and was able to narrow the issue down. It seems to happen only when:

      • Codex CLI (ChatGPT subscription) is selected as the AI provider, and

      • the workflow is set to copy, paste, or insert the output directly without opening a preview or chat window.

      Keeping every other setting the same and switching to a different provider fixes it. I tried OpenAI (via API), Claude Code (Claude subscription), Gemini, and OpenRouter. They all worked without any issues.

      With Codex CLI the workflow also works correctly if I enable the preview or or set the output to open in a chat window.

      So the issue seems specific to Codex CLI when the output is inserted directly. Hopefully this helps you isolate the issue.

      As for the feature flag you mentioned, I don't see that option in my interface. Here's what I'm seeing:

      Any idea why it might be missing? For reference, I'm on Version 2.16.0 (build 85).

        Thanks. That greatly helps! Ah my bad, I forgot that it’s a beta release and I haven’t pushed it to stable channel yet. Can you go to Settings > Updates, change the channel to Beta and click Check for Updates. This beta contains only a coupe of bug fixes so it should be relatively stable. I will promote it to the stable channel soon.

              Hi Daniel,

              I updated to the latest version, 2.17.1, enabled the feature flag you mentioned, and the workflows are working perfectly now. Thank you for your help. :)
