接近协议FunctionCallError(MethodResolveError(MethodNotFound))

Question

我是区块链、智能合约和近程协议方面的新手。我正试着向https://near.academy/学习。testnet上有一个样本合约: museum.testnet。

我使用的是windows，并且安装了wsl2。

我可以使用near login命令登录。但在那之后，当我调用near view museum.testnet getmemecount命令时，它给出了下面的错误。有人能在这方面帮我吗？

View call: museum.testnet.getmemecount()
An error occured
Error: Querying [object Object] failed: wasm execution failed with error: FunctionCallError(MethodResolveError(MethodNotFound)).
{
  "block_hash": "SZv8UsCeNXLkhjPa9KeZY6xJXmKNb6MLyKXqHVddiT5",
  "block_height": 65109663,
  "error": "wasm execution failed with error: FunctionCallError(MethodResolveError(MethodNotFound))",
  "logs": []
}

方法名称是get_meme_count，而不是getmemecount。请参阅博物馆here的源代码。

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

near学院的一些人提到它是getmemecount吗？
