title: Missing Env Value
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
In one of your pages you attempted to access an environment value that is not provided in the environment.
|
|
|
|
When accessing environment variables on the client they must be prefixed with `NEXT_PUBLIC_` to signify they are safe to be inlined for the client.
|
|
|
|
When accessing environment variables on the server in `getStaticProps`, `getServerSideProps`, or an API route the value must be provided in the environment at runtime.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
Either remove the code accessing the env value, populate it in your `.env` file, or manually populate it in your environment before running `next dev` or `next build`.
