My node-red-contrib-opcua client is showing invalid endpoint, check that server has security policy # None

I tried to use the OPCUA client of ThingsGateway to test that it can connect to Kepserver EX6 successfully, but the node-red opcua client of 0.2.315 version can't do that, I don't set any security strategies, anyone who knows how to solve that? I tried to revert the version of opcua but still failed. My node version is v18.18.0
