# FAQ: typical errors in deployment process
Deployment of software applications is a critical process that ensures the application is available. However, there are many things that can go wrong during the deployment process. In this page, we will highlight some **common errors** that occur during deployment and provide **solutions** for resolving them.
### Keys without \n in Environment Variables
One common error that occurs during deployment is when keys (such as **`LICENSE_SERVER_PUBLIC_KEY`**, **`JWT_PRIVATE_KEY`**, and **`JWT_PUBLIC_KEY`**) are passed to environment variables without **`\n`** at the beginning and at the end, as specified in the [`docker-compose.yml`](https://gitlab.com/whitespots-public/appsec-portal/-/blob/main/docker-compose.yml) file. This error can lead to the following error message:
**Solution:**
To fix this error, make sure that all keys that are passed to environment variables have `\n` at **the beginning** and **at the end**, as shown in the following example (from `docker-compose.yml`):
{% code overflow="wrap" %}
```yaml
