Issue with App Preview in UiPath Apps- Intermittent Loading Error

Feedback Apps
,
1

I am encountering an issue when trying to preview my UiPath app. The app loads but eventually displays an error message instead of proceeding to the preview. Interestingly, after multiple attempts, the app sometimes previews successfully. However, the issue reappears when I try to preview again, making it intermittent. I am continuously attempting to resolve this but haven’t identified a consistent workaround yet.

Has anyone else faced a similar issue, or is there a known solution for this intermittent preview failure?

Hi,

I saw this kind of error a while back. The reason I encountered it was because, in a strange way, I had 2 actions with the same name under an event (e.g. I had a button that was triggering some workflows and 2 of the Trigger Workflow actions had the same name).

Might be worth checking if this is the case for you as well.

This may helps you:

  1. Check the UiPath App Environment:

    • Ensure that you are using a supported version of the UiPath App and that your installation is up to date.
    • Perform checks on the server where the UiPath App is hosted, as server performance may impact app previews.

  2. Inspect Network Connectivity:

    • Intermittent issues could be due to network connectivity problems. Make sure you are on a stable internet connection and check for any issues that might be causing disruptions.
    • Perform a speed test and check for latency or packet loss.

  3. Browser Compatibility:

    • Ensure you are using a compatible browser and that it’s updated to its latest version. Sometimes caching issues can interfere, so try clearing your browser cache or using incognito/private mode to see if that resolves the issue.

  4. Console Errors and Logs:

    • Open the browser’s developer tools (usually F12) and check the console for any JavaScript errors or network request failures. This might give you insight into what’s failing.
    • Also, check the logs on the UiPath server for any errors or warnings during the app preview process.

  5. Reduce App Complexity:

    • If your UiPath app has a lot of elements or complex logic, try simplifying it temporarily to see if the preview issue resolves. This will help identify whether the app’s complexity is leading to the preview failure.

  6. Session Management:

    • Ensure that you aren’t running into session management issues where sessions are timing out or conflicting. Try logging out and back in, or close unused tabs/windows that might be holding sessions.

  7. Test Environment:

    • Try to replicate the issue in a different environment (e.g., a different machine or network) to determine if the issue is localized or there is a broader systemic issue.

  8. Check for Updates/Patches:

    • Sometimes bugs can exist in specific versions. Check the UiPath release notes or community forums to see if there have been reports of similar issues and if a patch or update has been released.
