title: Warnings
|
|
---
|
|
|
|
This is a list of warning output from NextAuth.js.
|
|
|
|
All warnings indicate things which you should take a look at, but do not inhibit normal operation.
|
|
|
|

|
|
|
|
## Client
|
|
|
|
#### NEXTAUTH_URL
|
|
|
|
Environment variable `NEXTAUTH_URL` missing. Please set it in your `.env` file.
|
|
|
|
:::note
|
|
On [Vercel](https://vercel.com) deployments, we will read the `VERCEL_URL` environment variable, so you won't need to define `NEXTAUTH_URL`.

|

|
|
|
|
## Server
|
|
|
|
These warnings are displayed on the terminal.
|
|
|
|
#### NO_SECRET
|
|
|
|
In development, we generate a `secret` based on your configuration for convenience. This is volatile and will throw an error in production. [Read more](https://next-auth.js.org/configuration/options#secret)
|
|
|
|
#### TWITTER_OAUTH_2_BETA
|
|
|
|
Twitter OAuth 2.0 is currently in beta as certain changes might still be necessary. This is not covered by semver. See the docs https://next-auth.js.org/providers/twitter#oauth-2
|
|
|
|
#### EXPERIMENTAL_API
|
|
|
|
Some APIs are still experimental; they may be changed or removed in the future. Use at your own risk.
|
|
|
|
## Adapter
|
|
|
|
### ADAPTER_TYPEORM_UPDATING_ENTITIES
|
|
|
|
This warning occurs when typeorm finds that the provided entities differ from the database entities. By default while not in `production` the typeorm adapter will always synchronize changes made to the entities codefiles.
|
|
|
|
Disable this warning by setting `synchronize: false` in your typeorm config
|
|
|
|
Example:
|
|
|
|
```js title="/pages/api/auth/[...nextauth].js"
|
|
adapter: TypeORMLegacyAdapter({
|
|
type: 'mysql',
|
|
username: process.env.DATABASE_USERNAME,
|
|
password: process.env.DATABASE_PASSWORD,
|
|
host: process.env.DATABASE_HOST,
|
|
database: process.env.DATABASE_DB,
|
|
synchronize: false
|
|
}),
|
|
```
