报错代码可以看到是这里，不过为什么返回值是errmsg=Success，但还是报错了。

pingcap/tiflash/blob/master/dbms/src/Storages/S3/S3RandomAccessFile.cpp#L93-L112


      
          auto & istr = read_result.GetBody();
          istr.read(buf, size);

          // Theoretically, `istr.eof()` is equivalent to `cur_offset + gcount != static_cast<size_t>(content_length)`.
          // It's just a double check for more safty.
          if (gcount < size && (!istr.eof() || cur_offset + gcount != static_cast<size_t>(content_length)))
          {
              LOG_ERROR(
