同样的代码，在VSCODE中就不报错，在咱们这就报错：Traceback (most recent call last): File “”, line 1248, in init_ctx File “”, line 62, in TypeError: Object of type coroutine is not JSON serializable sys:1: RuntimeWarning: coroutine ‘main’ was never awaited RuntimeWarning: Enable tracemalloc to get the object allocation traceback 请问是什么原因呢？想取得所有合约货币对名称 谢谢
