Steps to Reproduce

error-sankey-options.txt
Paste the options configuration in the link address into the official example

emphasis: {
focus: 'adjacency', // success
// focus: 'trajectory', // error
blurScope: 'coordinateSystem'
}

Setting "focus" to "trajectory" will cause the page to crash
（中文： 把链接地址里的options配置粘贴到官方示例里
emphasis: {
focus: 'adjacency', // success
// focus: 'trajectory', // error
blurScope: 'coordinateSystem'
}
focus设置为'trajectory'会导致页面崩溃）

Current Behavior

The nodes and links provided in the file can cause problems to occur（中文： 文件里提供的nodes和links会导致问题出现）

Expected Behavior

focus: Setting it as trajectory should not cause the page to crash. Although other data may be fine, the data I provided has this bug（中文： focus:设置为trajectory不应该导致页面崩溃，虽然别的数据可能没有问题，但是我提供的数据是有这个bug的）
