    I was getting th same issue and I adjusted my code to suit the outputs. Here's my JS solution:

        if(s.split(``).reverse().join(``) !== s){
        let half = Math.floor(s.length * 0.5);

        for(let i = 0; i < half; i++){
            let id = s.length - 1 - i;
            if(s.charAt(i) !== s.charAt(id)){
                let sub = s.substring(i,id);
                if(sub === sub.split(``).reverse().join(``)){
                    return id;
                }
                sub = s.substring(i+1,id+1);
                
                if(sub === sub.split(``).reverse().join(``)){
                    return i;
                }
                else{
                    break;
                }
            }
        }
    }
    return -1;
