Kadena域名注册智能合约REPL测试报错：with-read行未找到

问题场景 #

开发了Kadena Pact域名注册智能合约，通过REPL文件name.repl测试name.pact中free.testingdomain模块的域名注册功能。项目结构为：pact目录下包含主合约name.pact、测试文件name.repl，以及存放coin依赖模块的root目录。执行(load "name.repl")时，反复触发以下错误：

错误原因 #

错误日志显示，执行coin.transfer时，尝试读取目标账户k:36990b871267ec4532551e505260806d7f39378cebb5ea2c998c80301c5a100f的记录，但该账户未在coin表中创建，导致with-read操作失败。

解决方案 #

• 初始化费用接收账户：在name.repl的Tx1（Create KDA accounts）阶段，添加创建目标账户的代码。示例：

  (coin.create-account "k:36990b871267ec4532551e505260806d7f39378cebb5ea2c998c80301c5a100f" (read-keyset "fee-account-guard"))
  

  同时需要提前定义对应的keyset，确保账户有合法的guard。
• 校验合约中的转账目标地址：检查name.pact中transfer调用的目标地址是否正确，确认地址字符串没有拼写错误或生成错误。
• 确认权限能力配置：确保调用register函数时，已正确获取coin.TRANSFER能力，或者合约内部已正确处理转账所需的权限校验。
