    Hi,

    Does the error always occur on the same data?

    I had the same problem and added an exception capturing the data again.
    I don't know what changes per se, but it works.

    The data is so large, rows are larger than ruler.
    if reduce the rows quantity, the flow run OK.

    Hey @Andrewlu81 

    This error usually appears when you get a time out during extraction. In the February release we will be including a feature that will provide support for extraction from large tables.

    Hey @kostasc,

    Has this feature been released? I am still seeing this error when attempting to extract entire HTML tables with a large number of rows.

    I am also facing same issue. Even I reduced row to 1 only.

    Even then also same error.

    In UiPath its working flawlessly.
