Not sure if it is defect but I get the typeerror on this function; const lighthouseMetrics = await browser.getMetrics(); if I do not refresh the url

[bsuredigital]

async function captureAndAggregatePerformanceData(browser, strvalue) {
const currentUrl = await browser.getUrl();

if (!currentUrl || currentUrl === 'about:blank') {
    throw new Error("No URL loaded in the browser before attempting to capture metrics.");
}

const screenshotPath = `./reportgenerator/screenshotoutput/${strvalue}.png`;
await browser.saveScreenshot(screenshotPath);

const navigationTimings = await browser.execute(() => performance.getEntriesByType('navigation')[0]);
const fullLoadTime = navigationTimings.loadEventEnd - navigationTimings.fetchStart;

const performanceMetrics = await browser.cdp('Performance', 'getMetrics');

await browser.enablePerformanceAudits();

isLighthouseAuditRunning = true;  // Set the flag to true when Lighthouse audit starts
await browser.url(currentUrl);
const lighthouseMetrics = await browser.getMetrics();
isLighthouseAuditRunning = false; // Reset the flag once Lighthouse audit is done
lighthouseMetricsArray.push(lighthouseMetrics);

await browser.disablePerformanceAudits();

const aggregatedData = structurePerformanceData(strvalue, performanceMetrics, xhrData, fullLoadTime, lighthouseMetrics);
xhrData = [];
return aggregatedData;

}
