Class FRPolicyAbstract

Utility for processing policy failures into human readable messages.

Example:

// Create message overrides and extensions as needed
const messageCreator = {
  [PolicyKey.unique]: (property: string) => (
    `this is a custom message for "UNIQUE" policy of ${property}`
  ),
  CUSTOM_POLICY: (property: string, params: any) => (
    `this is a custom message for "${params.policyRequirement}" policy of ${property}`
  ),
};

const thisStep = await FRAuth.next(previousStep);

if (thisStep.type === StepType.LoginFailure) {
  const messagesStepMethod = thisStep.getProcessedMessage(messageCreator);
  const messagesClassMethod = FRPolicy.parseErrors(thisStep, messageCreator)
