使用长安链 Java SDK，创建连接失败maxInboundMetadataSize must be > 0
我创建了一个ChainClientDemo类,代码如下：
package com.example.sdk.client;
import org.chainmaker.sdk.ChainManager; import org.chainmaker.sdk.ChainClient; import org.chainmaker.sdk.SdkException; import org.chainmaker.sdk.config.*; import org.chainmaker.sdk.utils.FileUtils;
import java.io.IOException; import java.lang.reflect.Field; import java.util.ArrayList; import java.util.List;

public void testQueryBlockHeight() throws SdkException { String txId = "1861f32f5db1638aca690e1781c580f0203580a17604487880a967788ef5be0b"; long blockHeight = chainClient.getBlockHeightByTxId(txId, 2000); System.out.println("TxID 对应的区块高度: " + blockHeight); }

执行后，出现如下报错：
