Fetch Failed for db Client

[steven-tey]

Great work on this team!!

Following the example here gives me "Fetch failed" error when I'm trying to do it in Next.js API routes:

error - Error [TypeError]: fetch failed
    at Object.processResponse (evalmachine.<anonymous>:3033:34)
    at <unknown> (evalmachine.<anonymous>:3366:42)
    at <unknown> (node:internal/process/task_queues:141:7)
    at AsyncResource.runInAsyncScope (node:async_hooks:199:9)
    at AsyncResource.runMicrotask (node:internal/process/task_queues:138:8)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

However when I switched to the example in the blog post with import { connect } from "@planetscale/database"; it worked.

When you print the value of your DATABASE_URL environment variable, does it look like the following format? If the environment variable hasn't been set for the process, it's likely that it's trying to fetch a null URL and failing.

console.log(process.env['DATABASE_URL'])
// => mysql://<user>:<password>@<host>
