I found that in my case, the problem was that some parameters were missing here.

thisStep = {
      ...result.object, // add this line
      action: result.object.action,
      think: result.object.think,
      ...result.object[result.object.action]
} as StepAction;

thisStep = {
      ...result.object, // add this line
      action: result.object.action,
      think: result.object.think,
      ...result.object[result.object.action]
} as AnswerAction;

Actually, there was an answer, but it was not returned.
