PlatformException(400, 400 Key: 'GetUsersInfoReq.OperationID' Error:Field validation for 'OperationID' failed on the 'required' tag

flutter 我调用 OpenIM.iMManager.login 里面 try {
return this.userInfo = await userManager.getSelfUserInfo();
} catch (error, stackTrace) {
log('login e: $error s: $stackTrace');
if (null != defaultValue) {
return this.userInfo = await (defaultValue.call());
} 包错 我获取会话列表是空的
