Index was out of range. WB 5 Error

rado98 Contributor

I started getting the following error on one of my jobs: "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index". Any idea about what it means.


I beilve it is related to the Lookup transform used in the job


I havent run the job nor made chagnes to the data sources for a couple of months, so I think is problby a new bug/issue with WB5.

    I would reach out to and send them the workbench logs, they can help you find out what the issue is

    HI @rado98  --


    I don't see this one often, but I do recall a time in Workbench where a lookup transform and mismatching data types caused a similar error. For example, if the column schema is set to "DOUBLE" and you try to insert a date value like 03/26/2019, you may get that error. I'd make sure there are no erroneous values coming in from the lookup.


    But yes, getting the error log files to Domo Support would probably be helpful. Let us know what you find.
