What is this error and why is the path not being searched?

Question

React

I import the component: The component works and is imported, but for some reason an error occurs: { "resource": "/d:/projects/111111111/frontend/src/components/Header/Index.js", "owner": "eslint" , "code": "import/no-unresolved", "severity": 8, "message": "Casing of ./../Button does not match the underlying filesystem. (import/no-unresolved)", "source ": "eslint", "startLineNumber": 4, "startColumn": 20, "endLineNumber": 4, "endColumn": 33 } Does anyone know what's wrong? UPD:
import Button from './../Button';
