Studio Web debug: live browser preview in Output panel has disappeared (Local Workspace + Chrome, serverless robot)

Help Studio Web

Hi all,

During a debugging session today, I noticed the live browser preview/screenshot that used to appear in the Output panel during a debug run has disappeared — the section that used to show it is now completely gone, not blank or collapsed, just absent. I can’t pin down exactly how long it’s been broken (my own recollection of “since when” kept shifting when I tried to nail it down), but it was working within the last day or two before today.

Environment:

  • Studio Web, Local Workspace tab
  • UiPath Assistant version 2026.0.197 (July 2026) — not updated since, so unlikely to be the cause
  • Debug runs show “Serverless environment detected” early in the log — robot executes in a Docker/serverless sandbox, not directly on my machine
  • Browser: Chrome
  • Activities used: uix:NClick, uix:NTypeInto, uix:NSelectItem (UI Automation Next package), wrapped in an NApplicationCard

What I’ve already checked:

  • Relaunched Chrome and UiPath Assistant — no change
  • No new browser extensions added recently
  • Checked for any Chrome window on other Spaces/Mission Control during a run — nothing appears anywhere
  • The automation itself still runs and completes successfully (confirmed via logs and, once persisted, the resulting state in the target web app) — only the visual preview is missing, not the underlying execution

Question:
Is this a known regression or an intentional change to how the debug Output panel works for serverless/Docker robot sessions? Is there a setting I’m missing to re-enable a live preview, or is this expected to only show static per-activity screenshots now rather than a live view? Any pointer to a changelog entry or related thread would help.

Thanks in advance.

Hi @Mickael_Gueron

I’m seeing the same behavior with the live browser preview disappearing from the Run Output panel.

From the current UiPath documentation, live streaming is still supposed to be available for UI Automation runs, so it doesn’t look like an intentional removal. I also couldn’t find anything in the recent Studio Web release notes mentioning its removal for Serverless/Docker runs.

Since the automation itself is still executing successfully, this looks more like a UI/regression issue with the live stream. I’d suggest trying the same workflow with On local machine to see if the preview comes back. If it does, that would help confirm it’s specific to the Serverless execution environment.

@Monali_Vekariya, thanks for the suggestions - it works!
It’s slower than Debug on Cloud, let’s hope it will be fixed one way or another.

Thank you for confirming! I’m glad my suggestion worked and helped resolve the issue. Happy to help! :blush:
