Corda 4.3 client rpc throw error when we use LinearStateQueryCriteria to query by linear id - spring-boot

Question

I am trying to invoke a get by linear id for a state from a springboot application using corda rpc client. cordapps are build using corda 4.3.
Below is the query i use:
QueryCriteria queryCriteria =
new QueryCriteria.LinearStateQueryCriteria(null, idList, status, contractStateTypes);
List<StateAndRef<DemoState>> stateAndRefs = cordaRPCOps.vaultQueryByCriteria(queryCriteria, stateType).getStates();
The query fails to retrive data and throws an exception as shown below, but if i use Corda 4.1 rpc client the same query returns a correct result.
Below is the exception shown in the corda node logs when using corda rpc 4.3:

Any pointers as to how we could get this running using corda rpc 4.3?

Answer 1

It seems you are using CordaRPC 4.3 while your Corda node is running v4.1. In such cases, you need to provide the minimumServerProtocolVersion to CordaRPCClientConfiguration.
Here's a sample code:
CordaRPCClientConfiguration config =
new CordaRPCClientConfiguration(Duration.ofMinutes(3), 4);
CordaRPCOps rpcProxy = new CordaRPCClient(NetworkHostAndPort.parse("<host>:<port>"), config)
.start(<username>, <password>).getProxy();
Note the part CordaRPCClientConfiguration(Duration.ofMinutes(3), 4), "4" here is the minimumServerProtocolVersion supported which Corresponds to Corda 4.0.
