shardingsphere config XA-transaction with openGauss-server. After shardingsphere is started successfully, the client cannot establish a connection. Is server.yaml is correct? ### Which version of ShardingSphere did you use? 5.1.3 ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-Proxy ### Expected behavior The client successfully establishes a connection ### Actual behavior An error is reported on the client and server   ### Reason analyze (If you can) ``result = null`` cause a nullpoint error.  ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. server.yaml ```C++ rules: - !AUTHORITY users: - root@%:root - sharding@:sharding - zhoucong@:zhoucong provider: type: ALL_PRIVILEGES_PERMITTED - !TRANSACTION defaultType: XA providerType: Narayana props: max-connections-size-per-query: 1 executor-size: 16 proxy-frontend-flush-threshold: 128 # The default value is 128. sql-show: true proxy.transaction.type: XA ``` config-sharding.yaml ```C++ dataSources: ds_0: connectionTimeoutMilliseconds: 10000 idleTimeoutMilliseconds: 10000 maxLifetimeMilliseconds: 1800000 maxPoolSize: 200 minPoolSize: 10 password: Huawei@123 url: jdbc:opengauss://XXX.XXX.XXX.XXX:12102/d1?serverTimezone=UTC&useSSL=false&connectTimeout=10 username: test ds_1: connectionTimeoutMilliseconds: 10000 idleTimeoutMilliseconds: 10000 maxLifetimeMilliseconds: 1800000 maxPoolSize: 200 minPoolSize: 10 password: Huawei@123 url: jdbc:opengauss://XXXX.XXX.XXX.XXX:12102/d2?serverTimezone=UTC&useSSL=false&connectTimeout=10 username: test rules: - !SHARDING defaultDatabaseStrategy: none: null defaultTableStrategy: none: null shardingAlgorithms: ds_t1_alg: props: algorithm-expression: ds_${ds_id % 2} type: INLINE ts_t1_alg: props: algorithm-expression: ts_${ts_id % 3} type: INLINE tables: t1: actualDataNodes: ds_${0..1}.ts_${0..2} databaseStrategy: standard: shardingAlgorithmName: ds_t1_alg shardingColumn: ds_id tableStrategy: standard: shardingAlgorithmName: ts_t1_alg shardingColumn: ts_id schemaName: sharding_db ``` run maven ```C++ clean install package -Prelease -T1C -DskipTests -Djacoco.skip=true -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true -Drat.skip=true -DskiplTs -B ``` start shardingsphere successfully  client can't connect to shardingsphere   ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
