    const tblArticle = {
      Name: this._indexedDBLiveDBTableName,
      Columns: [
       {
          Name: 'ParentName',
          NotNull: true,
          DataType: 'string'
        },
        {
          Name: 'ChildName',
          NotNull: true,
          DataType: 'string'

For anyone else who is having this same issue and is actually passing a valid key, it could actually be that you are running.

objectStore.put(key, value)

when you should run

objectStore.put(value, key)

It's in reverse by the specs.

It is due to the invalid value supplied. IndexedDB support list of value - numbers, dates, strings, binary data, array : which are valid keys.

This error is generally thrown when you are passing - boolean,null or undefined value.

Check out w3c for more info - https://w3c.github.io/IndexedDB/#key-construct
