The first transport kind input transport for the first operator name operator does not match the second transport kind output transport for the second operator name operator, but they are located in the same partition.

The two operators are in the same processing element, but the input transport kind of the operators is different. The input transport kind must be the same for all the operators in a processing element.
Ensure that the input transport kind of the operators is the same, or that the operators are in different processing elements.
