Error: Unable to retrieve URL from environment variable UPSTASH_REDIS_REST_URL in the parsing process

Encountering an issue with TypeScript while attempting to create a new Redis instance. I've set up an .env.local file with matching names for the redis URL and token.

import { Redis } from '@upstash/redis'

export const db: Redis = new Redis({
  url: process.env.UPSTASH_REDIS_REST_URL,
  token: process.env.UPSTASH_REDIS_REST_TOKEN
})

The error message reads:

No overload matches this call.
  Overload 2 of 2, '(requesters: Requester): Redis', gave the following error.
  Argument of type '{ url: string | undefined; token: string | undefined; }' is not assignable to     parameter of type 'Requester'.
      Object literal may only specify known properties, and 'url' does not exist in type 'Requester'.ts(2769)
(property) url: string
UPSTASH_REDIS_REST_URL

Any suggestions on how to resolve this issue?

I've researched various sources but unable to make the error go away...

Answer №1

Ensure to always validate your environment variables before utilizing them in your code:

if (process.env.MY_ENV_VAR == undefined)
  throw new Error('MY_ENV_VAR is not defined!')
if (process.env.ANOTHER_ENV_VAR == undefined)
  throw new Error('ANOTHER_ENV_VAR is not defined!')
