I found the error. It was because of some missing libraries need. I discovered this when I downgraded playwright to version 1.9 and ran the the code then this was the error msg:

Nowadays, automation is becoming integral to the overall quality of the products being developed. Especially for mobile applications, it’s even more important to implement automation robustly.
Having a good web design can empower business and make your brand stand out. According to a survey by Top Design Firms, 50% of users believe that website design is crucial to an organization’s overall brand. Therefore, businesses should prioritize website design to meet customer expectations and build their brand identity. Your website is the face of your business, so it’s important that it’s updated regularly as per the current web design trends.
Sometimes, in our test code, we need to handle actions that apparently could not be done automatically. For example, some mouse actions such as context click, double click, drag and drop, mouse movements, and some special key down and key up actions. These specific actions could be crucial depending on the project context.
Joseph, who has been working as a Quality Engineer, was assigned to perform web automation for the company’s website.
Ever since the Internet was invented, web developers have searched for the most efficient ways to display content on web browsers.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
