Missing/broken images within communities courses

Background

Within the Serverless Framework website, we have community courses.

Expected behavior

When I go to https://www.serverless.com/courses/ for Community Courses, the user should see all examples with:

• course image (most likely in most cases pointing to udemy servers),
• course title.
• course description

Actual behavior

For some of the courses hosted on Udemy there are broken/missing images:

Affected courses:

• AWS Lambda and the Serverless Framework - Hands On Learning!
• Practical beginners course to Serverless Applications
• The Serverless Framework with Node.js & AWS
• AWS Lambda Serverless Framework Simplified For Beginners
• Build Serverless APIs with Serverless Framework and NodeJs

Source Image

When you will try to open the image in the new tab you will see:

Error from Udemy, so most probably is something on Udemy end.

Open https://www.serverless.com/courses/ and compare the five affected Community Courses with their Udemy image URLs. First locate the source for the course listings; no file or test is named in the issue. Done means every listed course displays its course image, title, and description, or has an agreed replacement when Udemy's image is unavailable.
