使用Google Api发现服务进行服务呼叫时出错

Question

我正在接受服务电话

＆＃34;可选（错误域= com.google.GTLJSONRPCErrorDomain代码= 404 \＆＃34;（未找到）\＆＃34; UserInfo = {error =未找到，NSLocalizedFailureReason =（未找到），GTLStructuredError = GTLErrorObject 0x600000655870：{message：\＆＃34; Not Found \＆＃34; data：[1] code：404}}）＆＃34;

可能是什么原因？

类如下

@implementation GTLServiceMovier
- (instancetype)init {
   self = [super init];
    if (self) {
   // Version from discovery.
     self.apiVersion = @"v2";
   self.rpcURL = [NSURL URLWithString:SERVER_URL]
}
  return self;
}

@end


+ (instancetype)queryForSmartMovieWithObject:(GTLSmartMovieEndApiModelResult *)object {
if (object == nil) {
    GTL_DEBUG_ASSERT(object != nil, @"%@ got a nil object", NSStringFromSelector(_cmd));
    return nil;
}
NSString *methodName = @"mvi.get.movies.start";
SmartMovieQuery *query = [self queryWithMethodName:methodName];
query.bodyObject = object;
query.expectedObjectClass = [GTLSmartMovieEndApiModelResult class];
return query;

}
