the heart of the matter, causing the second error is this: https://github.com/BryanWilhite/songhay-core/blob/master/src/utilities/display-item.utility.spec.ts#L132

background-compile-time error message:

Conversion of type '{ description: string; displayText: string; groupDisplayText: string; groupId: string; id: string; inceptDate: string; map: { "topic-enterprise-data": string; "group-year-month-2012-09": string; ... 86 more ...; "group-year-month-2012-08"?: undefined; }; modificationDate: string; sortOrdinal: string; childItems: any...' to type 'MenuDisplayItemModel' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
  Type '{ description: string; displayText: string; groupDisplayText: string; groupId: string; id: string; inceptDate: string; map: { "topic-digital-production-web": string; "group-year-month-2014-09": string; ... 86 more ...; "group-year-month-2012-08"?: undefined; }; modificationDate: string; sortOrdinal: string; childIte...' is not comparable to type 'MenuDisplayItemModel'.
    Types of property 'inceptDate' are incompatible.
      Type 'string' is not comparable to type 'Date'.ts(2352)

it looks like the JSON being loaded by Typescript is no longer auto-magically converted to DateTime:

"inceptDate": "2012-09-17T12:32:00",
