Hi All,

I am facing the below mentioned error while using the CV Extract Data Table Activity, strange thing is this that its working till the 7th Page of the ACME Work Items, but as it goes to the 8th Page its throwing the COM Exception Error, i am using delay before and general delays as well in the process

@Jai_Pande,

As per the error it’s failing at checkin Is visible.
Can you share how your workflow designed?

The image displays a UiPath workflow involving a CV screen scope with a "Do While" loop that includes a delay, table extraction, and text click actions. (Captioned by AI)

Also for the Do While Condition previously i was using output of CV Element Exists but now just using True for Testing Purposes
Thanks

  • UI not fully loaded before extraction.

  • Memory leak or UI element mismatch on later pages.

  • Selector inconsistency or CV model failing to recognize data on the 8th page.

  • Increase Delay:

  • Add a Delay (3–5 sec) before CV Extract Data Table on every page.

  • Use Element Exists or CV Element Exists to ensure table is fully loaded before extracting.

  • Split Extraction:

  • Extract data page by page instead of all at once.

  • Use Try Catch:

  • Wrap the CV activity in a Try Catch to handle the COM error gracefully and retry or skip the page.

  • Check Resolution & Scaling:

  • Make sure your robot screen resolution and scaling (100%) are consistent.

  • Restart ACME after 7th page:

  • As a last resort, refresh or reopen ACME app after 7 pages to clear memory/UI issues.

@Jai_Pande,

Try using Selection type Window instead of Element while indicating element through SC Scope activity.

The image shows a software dialog box titled "Selection Options" that instructs users on how to select elements, offering tips for detection issues and featuring settings for pause configuration, selection type, and UI framework. (Captioned by AI)
