NRPdcpRrcEnb error, the packet has not been marked as NR packet

I am a beginner in OMNet++ and I want to simulate the Interdependent Cell-Free and Cellular Network (https://dl.acm.org/doi/abs/10.1109/MNET.2023.3336218) . The ICCN architecture divides the network into large coverage areas (macro cells), each anchored by a macro base station (MBS). These MBSs ensure basic network access and control. Within each macro cell, numerous smaller cell-free access points (CF- APs) are strategically placed and linked to the MBS via a high-speed connection (fronthaul). The MBS can serve users independently, or it can work together with the controlled CF-APs to efficiently handle user requests and optimize network resource usage based on user needs and the cost of operating each cell. I connected the MBSs and other BSs. However, in the simulation I am getting the error in the attached screenshot. I tried to use access points but gave error: "No transmission channel found in the connection path between gates"
