As per microsoft graph API documentation the createUploadSession graph API only return the URL where attachment can upload but how to upload attachment chunk by chunk in javascript? does anyone knows? Thanks in advance. I'm referring this reference
Here is the reference for attaching the Attachment to a post in JavaScript, Please refer this Document
const options = {
authProvider,
};
const client = Client.init(options);
const reply = {
post: {
body: {
contentType: 'text',
content: 'Which quarter does that file cover? See my attachment.'
},
attachments: [{
'@odata.type': '#microsoft.graph.fileAttachment',
name: 'Another file as attachment',
contentBytes: 'VGhpcyBpcyBhIGZpbGUgdG8gYmUgYXR0YWNoZWQu'
} ]
}
};
await client.api('/groups/1848753d-185d-4c08-a4e4-6ee40521d115/threads/AAQkADJUdfolA==/reply')
.post(reply);
Hope this helpful.
