You can re-run it till it eventually succeeds. But it is getting annoying now.

Looking at the error, i find reports for node nodejs/node#32463 and node-addon-api nodejs/node-addon-api#799
Here some other project solves it by switching from ArrayBuffer to Externals Bannerets/tdl#119

We could either test different node 16.x versions till we find one that is more stable, or we drag it over to openzim/node-libzim, cause that is probably what triggers it.

Seems to be a regression to me as we don't have changed anythin at node-libzim since many months.

We won't be able to solve this.
We would have to wait for some node 16.x or other update that fixes it.
But until then, node 16 reached end-of-life (september this year), while 18 is the current LTS.

I rather drop node 16 support and add node 19 (so we got current release and current LTS) than waste time with this.

@uriesk Not super happy to drop support of Node.js 16.x... but if there is a really good reason. OK for me. AFAIK we can not automated test so far for Node.js 19, last time I tried, somehow the action which should install it was not ready.

To conclude: OK for me to drop Node.js 16 (we should take care the doc, and necessary check of Node version should be implemented/updated). At the end Node.js 18 is still pretty recent.

Lets think about that in 1.13 then.
This bug is just an annoyance and not urgent.
