Token retornando null

Estou utilizando o insomnia e está retornando null.

package com.LBS.config.security;

import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class AuthenticationTokenFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {

        System.out.println(request);
        String token = recoverToken(request);
        System.out.println(token);

        filterChain.doFilter(request,response);

    }

    private String recoverToken(HttpServletRequest request) {
        String token = request.getHeader("Authorizarion");
        System.out.println(token);

        if (token == null || token.isEmpty() ){
            return null;
        }
        return token.substring(7, token.length());

    }
}
