key name [u'planks:5'] error机审求教怎么

MC热爱者集合地

错误码:40, 错误详情: ["file bench.json key name [u'planks:5'] error","file benchoutdoor.json key name [u'planks:5'] error","file chair1.json key name [u'planks:5'] error","file chair2.json key name [u'planks:5'] error","file chair3.json key name [u'planks:5'] error"]

这个实体keyname是什么？求教，我改了半天不知道是哪里出错了。不知道是行为包还是资源包错了。
