deleteFileId 的值为 cloud://jsy-test-tk8xa.6a73-jsy-test-tk8xa-1258939113/storeCover-jsyf4244-1555987045932.jpg
deleteFileId 为之前 wx.cloud.uploadFile success的 res.fileID
console.log("typeof", (typeof deleteFileId))
wx.cloud.deleteFile({
fileList: [deleteFileId],
success: res => {
console.log("删除成功，fileList",res.fileList)
},
fail: err => {
console.log("删除失败，deleteFileId", deleteFileId,"err", err)
}
})
控制台打印：
typeof string
删除失败，deleteFileId
err Error: errCode: -401003 api parameter type error | errMsg: parameter.fileList[clone] should be string instead of function;

感谢反馈，这是我们的内部 bug，是否是在 Array.prototype 上挂了 clone 方法？如果是的请先避免修改 Array.prototype，后续这个问题会修复
是的
谢谢！非常感谢，这个问题困扰了我两天，报错的内容我也反复的去想，但是就是没想过是因为 Array.prototype 上挂了 clone的原因。
抱歉这是我们的失误，让你困扰了这么久
请问您的问题解决了嘛，我也遇到了类似的问题，我的是把fileID存储到images数组中,然后点击获取到index后，使用fileList: [images[index]]来删除，也会报这个错误
错误提示说的很清楚了
console.log("typeof", (typeof deleteFileId))
打印的是 typeof string 数组中我是给的字符串啊
而且无论是我复制控制台打印的 deletefileId还是复制云开发控制台中文件的fileid 直接放到fileList中也是报这个错
