This configuration is static and evaluated at **build time**. However, the `ZITADEL_API_URL`, which is supposed to be used for additional whitelisted hostnames, is a dynamic environment variable only known at **run time**. This creates a fundamental conflict, making it impossible to add the user-provided URL to the configuration when building the public Docker image. Consequently, images like instance logos fail to load. The existing workaround uses a permissive wildcard pattern (`*.zitadel.*`). This is a significant security risk, as it could allow malicious actors to abuse the server as an open image-resizing proxy, leading to potential denial-of-service (DDoS) attacks or excessive costs. # How the Problems Are Solved This change disables the Next.js Image Optimization feature entirely by setting `unoptimized: true` in the `images` configuration. By doing this, Next.js will no longer attempt to optimize, cache, or validate remote image sources. Instead, it will pass the original image URL directly to the client. This approach resolves the issue by: 1. **Eliminating the need for `remotePatterns`**, which bypasses the build-time vs. run-time configuration conflict. 2. **Improving security** by removing the overly permissive wildcard pattern. 3. **Ensuring functionality**, as remote images now load correctly. The trade-off is the loss of performance benefits from Next.js image optimization, but I see this as an acceptable compromise to restore essential functionality and secure the application.
