New error: Type instantiation is excessively deep and possibly infinite.

This one's actually new in 3.8. There are some additional errors in 3.9 - I'll post them below.

https://github.com/davidkpiano/xstate/blob/2e0bd5dcb11c8ffc5bfc9fba1d3c66fb7546c4bd/packages/core/src/stateUtils.ts#L157

packages/core/src/stateUtils.ts:157:36 - error TS2589: Type instantiation is excessively deep and possibly infinite.

157   return getValueFromAdj(rootNode, getAdjList(config));
                                       ~~~~~~~~~~~~~~~~~~

packages/core/src/State.ts:181:12 - error TS2589: Type instantiation is excessively deep and possibly infinite.

181     return new State(config);
               ~~~~~~~~~~~~~~~~~

packages/core/src/interpreter.ts:208:5 - error TS2589: Type instantiation is excessively deep and possibly infinite.

208     this.parent = parent;
        ~~~~~~~~~~~~~~~~~~~~

packages/core/src/interpreter.ts:783:13 - error TS2345: Argument of type '{ type: string; data: any; }' is not assignable to parameter of type 'string | EventObject | Event<EventObject>[] | Event<EventObject>'.
  Object literal may only specify known properties, and 'data' does not exist in type 'EventObject'.

783             data: err
                ~~~~~~~~~

To repro:

1. yarn
2. tsc -b -f tsconfig.monorepo.json

Führe yarn und tsc -b -f tsconfig.monorepo.json in der verknüpften xstate-Revision aus. Lies zuerst packages/core/src/stateUtils.ts:157, packages/core/src/State.ts:181 und packages/core/src/interpreter.ts:208 sowie 783. Als erledigt gilt die Aufgabe, wenn die gemeldeten Fehler TS2589 und TS2345 im Reproduktions-Build nicht mehr auftreten.
