Also had to downgrade Node.js version in Pengu since it started to fail with:

But bumping its dependencies did not help.

Bisected that to to the following commit in Nixpkgs:

	commit 5ad0643e1c0b6ec442754b34316814ea212a76a3
	Author: R. Ryantm <ryantm-bot@ryantm.com>
	Date:   Thu Jul 14 10:05:53 2022 +0000

	    nodejs-18_x: 18.5.0 -> 18.6.0

And node.js:

	commit 0636f86eccdf1c343fe94c16926160dbdefa2553
	Author: npm CLI robot <npm-cli+bot@github.com>
	Date:   Fri Jun 24 18:21:50 2022 -0700
