i had this problem when provisioning ble_mesh assert sch_arb.c 890, param 00000000 00000000

[xuantu]

First my device is initialized to blufi mode, then i turned off blufi mode and initialized mesh network in node mode and used nrf mesh app to create mesh network. when i added my device to the mesh network got an error right after i got the net_key from nrf mesh :assert sch_arb.c 890, param 00000000 00000000
Please help.
Thank in advance.
