I am stuck on mobx : “4.15.7”

I get this error:

Uncaught TypeError: props.apiStore.data.entries is not a function

I found this issue: https://github.com/mobxjs/mobx/issues/1424

.entries() is also affected!

Non working code:

  return Array.from(props.apiStore.data.entries()).map((entry) => {
    let key = entry[0]
    let values = entry[1]
    return (<HeatPumpsTable apiStore={props.apiStore} gridName={key} products={values}/>);
  })

apiStore:

  @observable data: Map<string, IProduct[]> = new Map<string, IProduct[]>([]);

How to correctly iterate apiStore.data to render its elements?
