As shown above, I had the same issue too.
Clearly, the problem lies in mdbook build.

The createBookFromReadme.sh script consists of multiple build functions and it fails at buildAndServeBookLocally due to the mdbook build error as illustrated below:

Inspecting the SUMMARY.md file generated by createBookFromReadme.sh, we find that the highlighted line is the root cause of this issue. In fact, it's actually the first line of README.md:

To overcome this, we can add an Update heading to the start of README.md.

Hope it solved your issue.
