How to reference gap junctions in the configuration file

[MargauxCalice]

Hello,

I want to create a network of gap junctions and simulate it using the PointNet simulator, but I'm not sure how to reference the gap junctions in the configuration file.

I have created gap junction connections as follows:

net_pre.import_nodes(nodes_file_name=path_pre_h5,node_types_file_name=path_pre_csv)
net_post.import_nodes(nodes_file_name=path_post_h5,node_types_file_name=path_post_csv)


net_pre.add_gap_junctions(source=net_pre.nodes(pop_name='PV'), target=net_post.nodes(pop_name='SST'), connection_rule=connection_rule,resistance=1250)

net_pre.build()
net_pre.save_edge('network')

Then I referenced these gap junctions in the configuration file as follows:

    "networks": {
        "nodes": [
            {
                "nodes_file": "$NETWORK_DIR/test_net_nodes.h5",
                "node_types_file": "$NETWORK_DIR/test_net_node_types.csv"
            }
        ],
        "edges": [],
        "gap_juncs": [
        	{
        	"gap_juncs_file":"$NETWORK_DIR/test_net_test_net_edges.h5",
        	"gap_juncs_types_file":"$NETWORK_DIR/test_net_test_net_edge_types.csv"
            }
            
        ]

However, I am getting this error:

Thank you for your help!
