TypeError: issubclass() arg 1 must be a class询问 claude-3.7-sonnet 后，认为问题出现在 lagrange/utils/binary/protobuf/models.py 的如下函数中：
def _decode(typ: type[_ProtoTypes], raw):
if isinstance(typ, str):
raise ValueError(
f"ForwardRef '{typ}' not resolved. "
f"Please call ProtoStruct.update_forwardref({{'{typ}': {typ}}}) before decoding"
)
if issubclass(typ, ProtoStruct):
return typ.decode(raw)
...抛出异常时，此处 typ 类型为 list[lagrange.pb.message.rich_text.Elems] ，无法作为 issubclass 方法的第一个参数传入。
