flow-no-steps

[wizzard] flow "<flow>" has no steps. A wizard is its steps, so there is nothing to start on or to
finish. Add at least one step, or check that the definition arrived whole. …/errors/flow-no-steps

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

A wizard is its steps. With none there is nothing to start on, nothing to draw and nothing to finish, so a flow like this is almost always a definition that did not arrive whole: a server response that sent "steps": {}, a generator that filtered every step out, or a sub-flow written as a placeholder.

Give the flow at least one step:

{ "id": "signup", "steps": { "account": {} } }

If the empty flow came from a server, the fix is on the side that produced it.
