I am performing browser testing of an application to check if video is played correctly on both Windows chrome and MAC Safari, this piece of code works fine in chrome and even andriod-ios devices. In all the devices I see both url1 and url2 being triggered in hfired including on safari, but suprisingly on Safari a test case is being failed with error az is not defined due to this code but it is working fine on Chrome with the same details

validate=async(hfired,scenario,tracking)=>{
let flag = false;
if(tracking=='ON' && scenario!=exit){
const url1='https://example.com'

 hfired.forEach((temp)=>
 {
    if(temp.includes(url1) || temp.includes('https://abc.xyz')){
    flag=true;
    }
    });
    if(flag==false){
    throw new Error('Not defined');
    }
    }
    else{
    const url2='https://guess.it';
    hfired.forEach((temp)=>{
    if(!temp.includes(url2) {
    throw new Error('az is not defined');
    }
    });
 }
};

Is there some mistake in the script?
