You've uploaded wrong file. Error is related with view component. Error message is very descriptive. If you want, check one of the standard GrandNode payment plugins. You can install them successfully so you can check how the installation works.

I'm creating with an example of PayPal plugin but through errors.

Hi rafeeq,

Are you able to create the Razorpay plugin?
