plugin-teardown-failed

[wizzard] plugin "<name>" threw while being torn down. The function its init returned threw, and
every other teardown still ran. Fix that function, or remove the plugin from options.plugins.
…/errors/plugin-teardown-failed

Printed with console.error by destroy() in @wizzard-packages/core, with what the teardown threw as the second argument.

A plugin’s init may return a function, and destroy() runs each of them once. A provider in either binding calls destroy() when it unmounts, if it created the wizard. One teardown that throws does not stop the others: every plugin after it is still torn down, and destroy() itself returns normally. A teardown that returns a promise which rejects is reported the same way, after destroy() has returned.

Read the error logged beside the message. The usual cause is a teardown that assumes something init set up and that was never there - a listener on an object that does not exist on the server, or a handle that was already released. Fix the function, or remove the plugin from options.plugins.
