uniCloud.deleteFile 报错，不允许被访问

上传文件没问题，但删除文件的时候就报错，提示不允许被访问。。。

通过API上传的文件无法通过API删除，但手动在云存储上传的文件又可以通过API删除。。奇怪了

        methods: {  
            uploadFile() {  
                uni.chooseImage({  
                    count: 1,  
                    async success(res) {  
                        console.log(res);  
                        if (res.tempFilePaths.length > 0) {  
                            let filePath = res.tempFilePaths[0]  
                            //进行上传操作  

                            // promise  
                            const result = await uniCloud.uploadFile({  
                                filePath: filePath  
                            });  
                        }  
                    }  
                });  
            },  
            deleteFile() {  
                // 删除文件  
                uniCloud  
                    .deleteFile({

                    })  
                    .then(res => {});
