I am using sandbox account to test the product.

I am able to login successfully using reportgateway, also GetTransactionDetails() and GetSettledBatchList(). But I am not able to use GetUnsettledTransactionList()

It is C# code

var transactions = gate.GetUnsettledTransactionList();

It is giving Error processing request: E00001 - An error occurred during processing. Please try again.Error processing request: E00001 - An error occurred during processing. Please try again.

Please help.
