@Anelisa_Bolosha1,

This is being thrown due to string value you provided to DelayBefore of activity which is throwing this. It requires Double data type but you passed it String

Thanks,

@ashokkarale Thanks for your response, how would I go about finding this activity?

@Anelisa_Bolosha1,

It’s not an activity but common property of multiple Ui Related activities like get text, click etc.

I have UI related activities but they are commented out, could they still have an effect even its so?

@Anelisa_Bolosha1,

No it should not but I think Studio isn’t aware your that code is disabled. Save the workflow, Close it. Close all the Studio instances. Restart/Reopen the Project and try to run.

Sometimes older code gets cached in Studio memory and creates this weird issue.

Thanks,
