wallet initialization and signing transaction problem

[Kiong2002]

Hi there, I was wondering why after executing clause 'signedTx = await wallet.signTransaction(transactionParams)', signedTx stay pending status, which caused the signing transaction to fail. I think maybe it is because wallet is not initialized properly. Maybe it needs some connection like using some kind of proxy? NOTE: I am in China, and all the API requests I used were through proxy.
你好，我想问一下为什么执行'signedTx = await wallet.signTransaction(transactionParams)'语句后，signedTx保持pending状态，然后就无法签名？我感觉是因为wallet对象没有被初始化正确。我在中国，是不是wallet的初始化需要代理？（因为我其他的API请求都需要用代理）

@Kiong2002 你好，本SDK是离线签名，不涉及联网操作。问题中提到的“无法签名”具体是指什么呢，能否提供一下更详细的信息？
