Unexpected empty source on thymeleaf fragment that calls for a css file

right now i keep getting a smell (Unexpected empty source) on this fragment, lookis like sonarqube is not seeing the content in the fragment of the files
<style th:replace="fragments/1000/customerInvoice/styles :: styles" th:remove="tag"></style>
any ideas in how to solve it?


Could you explain what’s your code doing? what is “the fragment of the files”?
Does the file containing this code have .html extension?
