沒有 congestion 再加上 detail route 之前也都沒 violation 為何在 detail route 時會出現這麼多 violation 呢?

感謝版主大大的回覆 ~~ 版主大大所述我早知道... 且也做過了 ~~ 如此做是知道哪裡 violation & 得知 violation 的 status ,
: X0 o$ l  ]0 J8 ^4 ^( s6 v. _我現在想知道的是如何 Fix violation, 由 QueryError 得知的 Infomation , 並無助於如何 fix violation,
有哪位大大知道要如何 fix routing violation ?
