One or more error exception!

Each time when i try to execute a state machine in a loop like structure…say fetching emails from outlook one by one…a ui path error pops up as ‘One or more errors occurred’! Kindly help me with this!

Which activity is throwing this error ? Screen shot please

While debugging it seems that the error is occurring during the execution of click activity applied on that ‘continue’ button which is a web element.And the thing that confuses me is that this particular error is occasional. Note:The error returned by UiPath only says ‘one or more errors occured’.

Check out for selectors!
May I know what selector have u used?
