How to resove error of : Assign : Index was outside the bounds of the array

Dear all,

I have a question that when I tried to assign DataRow value into variables (GenericValue),
I got below error message…

Assign : Index was outside the bounds of the array.

How can I fix this? sorry for vague question but with my capacity it is the best I could describe in detail…


@Kn.opp this error occurs due to more element in the specified array size

Hi Kn.opp,

to give a bit more detail this error occurs when you are trying to access an index outside of the current bounds of the array.

e.g. you have an array of 5 items. (array {1,2,3,4,5}) if you try to get the item from index 10 (array(10)) you will get this error as there is actually only 5 indexes (the max being 4 as arrays start at 0).

Could you give more info on how you are assigning your data row into variables and we may be able to get you a fix.


Dear jakelewis18, indra

Thank you very much for your help here…!
I’ve tried assigin data row as attached… I hope this limited screenshot would be sufficient for your advise…

Thank you very much…

@Kn.opp, There might be a chance of returning a empty array of datarow (arrDataRowOfCsv3) after filtering. U are accessing an empty array with some index greater than zero, it returns this error.

Solution : Check the array count before you access it through index !

Hello Everyone
I create one script in studio and published it in orchestrator. In Studio, the script works fine, but in Orchestrator, it gives an error. “Throw: Unable to process Product data. Error Details : Index was outside the bounds of the array.”

But I have used “Use browser activity” not an array.

Can any one help me ?
Thanks in advance…
