It seems that the data contains duplicated Interchange Control Number. By default the connector will raise an error if that happens. If you want to ignore duplicates set in the configuration of the connector "Require unique interchanges" to false. The documentation of this configuration says:

Require unique Interchange Control Numbers (ISA13) for received interchanges. The normal behavior is to record the interchange numbers previously processed and reject any duplicate interchange numbers from the same partner (as determined by the interchange sender and receiver identification). If false, this instead allows processing of the received interchange to continue and leaves it to the application flow to track numbers and handle appropriately.
