When I run my Ktor app, I get this message in the log:
```ERROR ktor.application - Unhandled: GET - /favicon.ico
java.lang.NumberFormatException: For input string: "favicon.ico"```
Why is this happening? I never make a GET request for that file.

Your browser is automatically making that request to show the little icon on tabs that you see

How can I fix it (I don't have an HTML file, I use kotlinx.html)

If you wanted to add an icon, you would serve it as a static asset: <https://ktor.io/docs/serving-static-content.html|https://ktor.io/docs/serving-static-content.html>

Otherwise, you'd just need to update your code to not crash on non-numeric input and the icon would be blank
