clear-on-leave-invalid

[wizzard] clearOnLeave of step "<id>" is neither true nor a list of data paths. It is read when the
step is left, and any other value fails that navigation. Set it to true, or put the paths in a list.
…/errors/clear-on-leave-invalid

Returned by validateFlow as a problem with path: steps.<id>.clearOnLeave, and listed in the message of flow-invalid by assertFlow.

clearOnLeave says what to forget when a step is left, in one of two forms: true drops the step’s whole slice, and a list of strings drops those paths of data. A single string, false, or a list with anything but strings in it is neither, and a flow from a server can carry any of them because no type checked it.

{ "clearOnLeave": ["company.vat", "company.name"] }

For one path, wrap it in a list. To keep the data, which is the default, leave the field out rather than setting it to false.
