'HTTP/1.1 403 Forbidden', Unable to upload the document Adobe API serivces

[muhammad_7519]

This is my matlab code. I am not able to upload the document getting  the following error.

StatusLine: 'HTTP/1.1 403 Forbidden'
StatusCode: Forbidden
Header: [1×11 matlab.net.http.HeaderField]
Body: [1×1 matlab.net.http.MessageBody]
Completed: 0

However, using python or postman I can upload the document. There is something wrong with the Matlab script.

still looking for help

[Raymond Camden]

It's hard to grok what you are doing here as I've never used matlab. To be clear, are you able to make the asset, but can't upload it? If so, that's not really an Adobe API issue, but just uploading content in matlab itself.

[muhammad_7519]

I am really happy to see your kind reply.

Yes, you are right. I am not able to upload it, getting the error "HTTP/1.1 403 Forbidden"

Yes, it is proably matlab issue. I have been stuck here.

Any help in this regard or any wayout in this regard, would be highly appreciated.

[Raymond Camden]

The best I can do is shared the Node.js code I use for this step:

async function uploadFile(url, filePath, mediaType) {

	let stream = fs.createReadStream(filePath);
	let stats = fs.statSync(filePath);
	let fileSizeInBytes = stats.size;

	let upload = await fetch(url, {
		method:'PUT', 
		redirect:'follow',
		headers: {
			'Content-Type':mediaType, 
			'Content-Length':fileSizeInBytes
		},
		duplex:'half',
		body:stream
	});

	if(upload.status === 200) return;
	else {
		throw('Bad result, handle later.');
	}

}

I have the python script from the SDK, which is working pretty fine. The problem is with the matlab script, As I posted in thread

[muhammad_7519]

can you share the correct matlab code. or help me to correct the code, which I posted on the top?

[Raymond Camden]

I can't, as I don't use Matlab. I'm sorry. Maybe try their support forums?

[muhammad_7519]

ok, anyway thanks for your time
