Uploading files to meteor server using Method call - file

Question

I am trying to implement file uploads for meteor using Method call.
I am using this meteor package: https://atmospherejs.com/ostrio/files.
I have no problem on client side (I can send file in a base64 encoded format). on server side I am trying to implement this function : https://github.com/VeliovGroup/Meteor-Files/blob/master/docs/write.md
but I am getting this error.
Error during upload: TypeError: Images.write is not a function
Here is the code of my Method on server:
export const insertImage = new ValidatedMethod({
name: 'images.insert',
validate: new SimpleSchema({
file: { type: String },
}).validator(),
run({ file }) {
Images.write(file, {
fileName: 'sample.png',
type: 'image/png',
}, function (error, fileRef) {
if (error) {
throw error;
} else {
console.log(`${fileRef.name} is successfully saved to FS. _id: ${fileRef._id}`);
}
});
},
});

According to the lib documentation you will need to first instantiate Images with an instance of FilesCollection, similar to as following:
https://github.com/VeliovGroup/Meteor-Files#api-overview-full-api
import { FilesCollection } from 'meteor/ostrio:files';
const Images = new FilesCollection({
collectionName: 'Images',
allowClientCode: false, // Disallow remove files from Client
onBeforeUpload(file) {
// Allow upload files under 10MB, and only in png/jpg/jpeg formats
if (file.size <= 10485760 && /png|jpg|jpeg/i.test(file.extension)) {
return true;
} else {
return 'Please upload image, with size equal or less than 10MB';
}
}
});

I have used this syntax:
Meteor.call('images.insert', {
file: image
}, (err, res) => {
if (err) {
console.log(`Error during upload: ${err}`);
} else {
console.log(`Upload successfully!`);
}
});
