Using publicRuntimeConfig with target set to serverless

Why This Error Occurred

In the serverless target environment next.config.js is not loaded, so we don't support publicRuntimeConfig.

Possible Ways to Fix It

Use config option env to set build time variables like such:

// next.config.js
module.exports = {
  env: {
    special: 'value',
  },
}

// pages/index.js
console.log(process.env.special) // value
