The easy way of fixing this issue by editing the eslintrc file.
Fixing .eslintrc file
Add the following code to the eslintrc file.
{
"extends": ["next/babel", "next/core-web-vitals", "prettier"],
"rules": {
"react/no-unescaped-entities": "off",
"@next/next/no-page-custom-font": "off"
}
}
After adding the codes, the errors will eventually go.
