apply Floorplan error for 'model.find_consumer' when the consumer is AddStreams_Batch

[simplelins]

please check! the input of 'AddStreams_Batch' node are "StreamingDataWidthConverter_Batch_6_out0" and "StreamingDataWidthConverter_Batch_4_out0". when the node ' StreamingDataWidthConverter_Batch_4' find the consumer that return none, because the function find_consumer only select from input[0]
