近协议函数调用错误（MethodResolveError（MethodNotFound））

Question

我是区块链、智能合约和准协议方面的新手。我正在尝试向 https://near.academy/ 学习。 testnet 上有一个示例合约：museum.testnet.

我正在使用 windows 并且我安装了 wsl2。

我可以登录 near login 命令。但在那之后，当我调用 near view museum.testnet getmemecount 命令时，它在下面给我错误。谁能帮我解决这个问题？

View call: museum.testnet.getmemecount()
An error occured
Error: Querying [object Object] failed: wasm execution failed with error: FunctionCallError(MethodResolveError(MethodNotFound)).

  "logs": []
}

方法名称是get_meme_count，不是getmemecount。看博物馆源码here.

$ near view museum.testnet get_meme_count
View call: museum.testnet.get_meme_count()
67

near academy 有没有提到getmemecount？
