Jekyll build error

After seamless build processes on many occasions to date, today’s build of my jekyll site is failing with the following error:
fs.readFileSync(...).replaceAll is not a function
All I’ve done is add a line of text in one of the markdown files!! And building locally goes without hitch.
Any ideas? Thanks, in hope and expectation…

My guess is that it’s most likely a problem using npx staticrypt to password protect a page. But why should this suddenly break after working just fine on many previous occasions?

It was addressed by the author of staticrypt and all is working now
