Can someone help me out? I keep on receiving the error messages

Code snippet from background file
const siteUrl = "http://localhost/site_for_parsing";
chrome.runtime.onConnect.addListener(port => {
port.onMessage.addListener(msg => {
if(msg.message === 'analysis') {
chrome.tabs.create({active: false, url: siteUrl}, tab => {
chrome.scripting.executeScript({
target: {tabId:tab.id},
files: ['dist/parser.js']
}, (results) => {
chrome.tabs.sendMessage(tab.id, {msg: "analysis background"}, res => {
port.postMessage(res)
chrome.tabs.remove(tab.id)
})
})
});
}
});
});
I would greatly appreciate your assistance! Looking forward to your responses. Have a wonderful day!
