bug-fix : Custom generateFilename is Not working

[GwonHyeok]

when using generateFileName as Storage option
generateFilename option is not working

because keystone-storage-adapter-s3 can be used only DEFAULT_OPTIONS.generateFilename
So I made the generateFilename option to work
thanks you

const storage = new keystone.Storage({
    adapter: require('keystone-storage-adapter-s3'),
    s3: {
        path: '/files',
        region: 'ap-northeast-1',
        headers: {
            'x-amz-acl': 'public-read'
        },
    },
    schema: {
        bucket: true,
        etag: true,
        path: true,
        url: true,
    },
    generateFilename: customGenerateFileName // it does not working
});

@GwonHyeok this looks like a configuration issue, not a bug in the s3 adapter:

generateFilename should be passed in the s3 options, not the top level. Like this:

const storage = new keystone.Storage({
    adapter: require('keystone-storage-adapter-s3'),
    s3: {
        path: '/files',
        region: 'ap-northeast-1',
        headers: {
            'x-amz-acl': 'public-read'
        },
        generateFilename: customGenerateFileName, // <-- here
    },
    schema: {
        bucket: true,
        etag: true,
        path: true,
        url: true,
    },
});
