npm ls mockery

2. No fixed release: DOWNGRADE to a release before 2.1.0

npm view mockery versions npm install mockery@"<2.1.0"

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.
