`npm ERR! code ELSPROBLEMS`

I've noticed the "Node.js CI" badge on the README is red (failing):

Clicking on the badge leads to https://github.com/nodejs/citgm/actions?query=workflow%3A%22Node.js+CI%22 and the most recent runs on main are green:

Clicking on one of the green builds shows annotations even though the subjobs are all green:
e.g. https://github.com/nodejs/citgm/actions/runs/6347014207

Clicking on one of the annotations shows that npm is returning exit code 1 in the "Print installed dependencies" step.
e.g. https://github.com/nodejs/citgm/actions/runs/6347014207/job/17241378354#step:12:991
