Validation error in sequence activity

while running automation regarding Extract data from PDF file I am getting following massage.

Validation error "one or more children have validation error " showing in sequence activity.
what is validation error ? how to mitigate it

Look at the activities inside the Sequence. That message means one or more of the activities inside the Sequence aren’t configured correctly.

Hi @Deepak_Raul1

Can you please check the child activities, there should be one activity or more which might be showing a red caution sign or top right.

Try zooming out a. Bit if the whole sequence isn’t visible to you.

Thanks

You can also click on the error on the sequence and it should focus you to the child activity with the error.
