I met some errors about "reading meter spec from target" when ONOS connects to stratum installed on tofino,

[xfyan0408]

In ONOS cli, I can verify that the onos connects to stratum installed on tofino correctly, but stratum cli returns some errors of Failed to read forwarding entries from node 1: Error when reading meter spec from target

some error logs from stratum are as follows:
