Near Protocol FunctionCallError(MethodResolveError(MethodNotFound))

Question

I'm new in blockchain, smart contract and near protocol. I'm trying to learn from https://near.academy/ . There's a sample contract on testnet : museum.testnet.

I'm using windows and i installed wsl2.

I can login with near login command. But after that, when i called near view museum.testnet getmemecount command its giving me error below. Can anyone help me on this?

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

  "logs": []
}

The method name is get_meme_count, not getmemecount. See the source code of the museum here.

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

Does some part of near academy mention it as getmemecount?

Thanks very much. I realized this in transaction after 1 day. And yes academy document says : , 4. Now the contract name is "museum.testnet" and the method is called getmemecount. So type: near view museum.testnet getmemecount. This will return you the amount of memes that are registered in the museum. 5. Congratulations. You just called a contract on NEAR. near.academy/near101/chapter-4 – Moldy
