README

This application uses modified `EcsLayout.json` with the only difference of truncating the stacktrace:
```text
"error.stack_trace": {
"$resolver": "exception",
"field": "stackTrace",
"stackTrace": {
"stringified": {
"truncation": {
"pointMatcherStrings": ["at javax.servlet.http.HttpServlet.service"],
"suffix": "\n\t"
}
}
}
}
```

To reproduce the issue run the application:
```bash
./gradlew bootRun
```
and make a request:
```bash
curl http://localhost:8080
```
