postcss-preset-env: end value has mixed support, consider using flex-end instead

Question

Any suggestion how to resolve this warning? I checked the whole project no where i used anything like

justify-conten: end or align-items: end and etc.

Still not sure why this warning showing everytime.

Using the following versions in Angular 13

"postcss": "^8.3.11",
"tailwindcss": "^2.2.19",

EDIT/UPDATE:

It turns out it was the issue the package I am using. It was not in my code.

If you're using (S)CSS or SASS, you have to write flex-start or flex-end instead of start or end respectively.

Like this:

justify-content: flex-end;
align-items: flex-end;
