cd /opt/browserless
npm ci --include=optional --include=dev --prefix /opt/browserless

if this doesnt work -> Report to Browserless Repo

Thanks, that didnt work, but I used:

cd /opt/browserless
npm install --save-dev typescript
npm run build

Now I am getting another error:

[ERROR] in line 159: exit code 0: while executing command "$@" > /dev/null 2>&1

[MickLesk]

heh? The issue is supressed, why? Its not from the script

[m3tc0n]

Do you know what is happening?

I'm seeing the same ⠹ Updating Browserless (Patience) [ERROR] in line 159: exit code 0: while executing command "$@" > /dev/null 2>&1 error when updating change detection (via the LXC update command)

[m3tc0n]

I have installed a new instance of change detection.

[MickLesk]

Has anyone reported this to browserless Repo?

[xyzulu]

Surely this is related to: #8011 ? I've not reported this as I don't have a full handle on the issue. The tsc not found is not an issue for me.. only the error on update: [ERROR] in line 159: exit code 0: while executing command "$@" > /dev/null 2>&1

Really, this issue should have the tittle changed. In any case, sorry.. I want to help but don't have the cycles to dig in yet.

I successfully updated ChangeDetection by downloading and editing the script to use an older npm version. As it seems the latest npm version (11.6.1) has introduced a bug with optionalDependencies.
Mentioned here: npm/cli#8628

  NODE_VERSION="24" setup_nodejs

  # Force specific npm version
  msg_info "Installing npm 11.6.0"
  $STD npm install -g npm@11.6.0
  msg_ok "Installed npm 11.6.0"

Its the Same error, only supressed with verbose mode

[MickLesk]

Since no one is reporting it to the browserless repo, I will close the issue tonight. Then you'll have to live with it, or wait until it fixes itself.

This is not an external Browserless issue. The root cause is in the update script itself.

The update script in changedetection.sh has a logic error at line 60:

$STD npm ci --include=optional --include=dev --prefix /opt/browserless
$STD npm run build --prefix /opt/browserless
$STD npm run build:function --prefix /opt/browserless
$STD npm prune production --prefix /opt/browserless  # ← This removes TypeScript!

Workaround:

cd /opt/browserless
rm -rf node_modules package-lock.json
npm install --include=dev
npm run build
systemctl restart browserless
