[SOLVED] npm show version throws error ERR_STRING_TOO_LONG Cannot create a string longer than 0x1fffffe8 characters

Issue

i have a cron that compare the version of an npm package installed on the server with the latest version on my private registry (verdaccio) and update the package accordingly

REMOTE_VERSION=$(npm show ${PACKAGE_NAME} version)
LOCAL_VERSION=$(node -pe "require('./package.json').version")
...

This cron run without problem on all of my servers except for one where the command npm show ${PACKAGE_NAME} version throws the error:

npm ERR! code ERR_STRING_TOO_LONG
npm ERR! Cannot create a string longer than 0x1fffffe8 characters

I have read here that 0x1fffffe8 is exactly 512MB, but the response of that command is just 4/5 chars (like "v0.1.50"), so it seems strange that it can exceed that limit. Moreover the same command (for the same package) run smoothly in local and all other servers

Here are some specs. of the server

NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"

Node v14.17.3
npm v6.14.13
nvm v0.38.0
pm2 v5.1.0

Solution

Upgrading to node 16.18.0 solve the issue.
