我已经从 fabric-samples 实例化了一个示例 NodeJS 链代码，marbles02所有调用和查询函数都工作正常，但是当我试图查询这个函数queryMarblesWithPagination时，它给了我这个错误：

Error: endorsement failure during query. response: status:500 message:"transaction returned with failure: TypeError: stub.GetQueryResultWithPagination is not a function"

我的链码日志是：

Args: ["queryMarblesWithPagination","{\"selector\":{\"owner\":\"tom\"}}","3",""]
{ fcn: 'queryMarblesWithPagination',
  params: [ '{"selector":{"owner":"tom"}}', '3', '' ] }

我认为示例中有一个“错字”-函数名称应以小写g开头-getQueryResultWithPagination

我在 stub.js 中看到的是函数名称以小 g 开头而不是大写 G。因此，stub.GetQueryResultWithPagination您应该尝试而不是调用stub.getQueryResultWithPagination。这应该可以解决您的错误。
