razorpay-node: Unable to capture payment

I am using version 1.2.0 and trying to make payment using instance.payments.capture, however it throws following error -

(node:5715) Warning: a promise was rejected with a non-error: [object Object]
{ statusCode: undefined, error: undefined }

If I check on the dashboard then under payments tab, I can see the payment getting authorised and using the same payment_id and amount (in paise) if I make the request, it still throws the same error. I have reset the API Key and Secret too before sending a fresh request. But no success. It would be great if at least proper error message is shown so that it will be easier to debug.

Let me know if you want any other details.
