Hi @Shohei Nakata , can you share your OML or a sample with the thing that you are trying to do?

Hello @Shohei Nakata,

The 'ArgumentOutOfRange' exception can happen for a variety of reasons. Since you mentioned you are doing a bulk insert the likely root causes 'may' be:

1. If you have invalid data for e.g. a badly formed/ invalid date.

2. If there is a data type or attribute name mis-match.

3. If you are referencing a value in a list by its index number or attempting to add a value using an index number, and the index number is invalid.

4. If you try to extract a substring that is outside the range of a given string.

Hope that gives you an idea of where to look for a root cause,

Regards,

AJ

The exception that is thrown when the value of an argument is outside the allowable range of values as defined by the invoked method. Indexing an empty list will always throw an exception. Use a method like Add to append the item to the end of the list, or Insert to place the item in the middle of the list somewhere, etc. You cannot index into a C# list if that offset doesn't exist.

Typically, an ArgumentOutOfRangeException results from developer error. Instead of handling the exception in a try/catch block, you should eliminate the cause of the exception or, if the argument is returned by a method call or input by the user before being passed to the method that throws the exception, you should validate arguments before passing them to the method.
