Attachments returning a 401 signature_invalid error

[tommaitland]

I'm trying to use the attachment endpoints which are in this wrapper, and I'm posting this with the understanding they're not properly supported yet – but thought someone might be able to help.

I can't seem to get around this error:

I've read the code and am posting like this:

      let stats = fs.statSync(`/tmp/myfile.pdf`);

       // upload the attachment
        let attachment = xeroClient.core.attachments.newAttachment({
            MimeType: 'application/pdf',
            FileName: `myfile.pdf`,
            ContentLength: stats.size
        })

        return attachment.save(`/Invoices/${invoice.response.Id}`, `/tmp/myfile.pdf`)

The return is consistently this:

{ Error: POST call failed with: 401
    at /user_code/node_modules/xero-node/lib/application.js:129:42
    at passBackControl (/user_code/node_modules/xero-node/lib/oauth/oauth.js:400:25)

  data: 
   { oauth_problem: 'signature_invalid',
     oauth_problem_advice: 'Failed to validate signature' } }

I've tried the endpoint using another wrapper (npm/xero) and I'm getting the same error, I'm wondering if neither support signing for attachments – or am I doing something wrong?

Hi @tommaitland .

I've just fixed this in the latest version 2.1.0. Please update your dependencies and your code should start working.

You can find an example of how to use attachments in the Github Docs here

Please close this issue if it meets your requirements, or update if you're still having problems.

Thanks

Jordan

Closing this off as it's now a supported feature. Please raise another issue if needed.

Thx!
