I am still unable to reproduce the problem.

```bash
$ node --version
v18.9.0

$ npm --version
8.19.1

$ asciidoctor --version
Asciidoctor 2.0.16

$ hugo version
hugo v0.102.3-b76146b129d7caa52417f8e914fc5b9271bf56fc+extended linux/amd64

That makes no difference… `npm install` still throws errors. Downgraded node.js to v14.19.3 and had the same problem.

Sorry, but I can’t spend any more time on this. As stated earlier, the page is not truncated when running asciidoctor as a stand-alone application. Your problem seems to be related to running asciidoctor through node/npm.

Yes, I use the stand-alone application asciidoctor to avoid this problem

I circumvented the problem, but did not solve it.  
But still, thank you.

this resolve it
