I followed the instruction at https://github.com/alexa/skill-sample-nodejs-city-guide/blob/master/instructions/1-voice-user-interface.md for implementing the city guide skill.
But I got the following response in Alexa device:
"There was a problem with the requested skill's response"
On testing the Lambda function, I get the following error:
"errorMessage": "Cannot find module 'i18next'",
How do I make this module available to the function? I had just followed the instructions and chosen deploy to alexa-skills-kit-nodejs-factskill. The resources were built automatically.
