File upload example for javascript returns No file found in request.

[LindaLawton]

I tried to run the file upload example for javascript

The file exits as i added a check for it

// Check if the file exists
if (!fs.existsSync(filePath)) {
    console.log(`File '${filePath}' does not exist` );
}

When i run the sample i get

GaxiosError: No file found in request.

Update

I did find that this works loading just the file path.

const media = {
        mimeType: mime.lookup(filePath),
        body: filePath,
    };

It seams its the loading the stream thats not working.

Hi Linda - thanks for reporting this. I'd like to understand the issue with fs.createReadStream a bit more. Can you try running the sample code from the repo and see if that succeeds? If not can you provide the error and what env you're running with? readme
