I followed the steps in https://developers.ringcentral.com/guide/notifications/webhooks/quick-start to create webhook-notification.js but when I run the resulting file, it fails with MODULE_FOUND
~/ringcentral $ node ./webhook-notification.js internal/modules/cjs/loader.js:888 throw err; ^ Error: Cannot find module '@ringcentral/sdk' Require stack: - /home/x/ringcentral/webhook-notification.js at Function.Module._resolveFilename (internal/modules/cjs/loader.js:885:15) at Function.Module._load (internal/modules/cjs/loader.js:730:27) at Module.require (internal/modules/cjs/loader.js:957:19) at require (internal/modules/cjs/helpers.js:88:18) at Object.<anonymous> (/home/x/ringcentral/webhook-notification.js:2:21) at Module._compile (internal/modules/cjs/loader.js:1068:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1097:10) at Module.load (internal/modules/cjs/loader.js:933:32) at Function.Module._load (internal/modules/cjs/loader.js:774:14) at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:72:12) { code: 'MODULE_NOT_FOUND', requireStack: [ '/home/x/ringcentral/webhook-notification.js' ] }
I'm new to node.js so if there is a trivial error in the example code, I might have missed it.
