Fixed in: 1.123.48, 2.21.8, 2.22.4

Safe to downgrade to: a release before 2.0.0

1. Check installed version

npm ls n8n

2. UPGRADE to 1.123.48

npm install n8n@">=1.123.48"

3. If no update is available yet, DOWNGRADE to a release before 2.0.0

npm view n8n versions npm install n8n@"<2.0.0"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
