Populate nested components

This is a single type i created


I have dynamic zone block and inside block i have two component comp1 and comp2. In comp1 there are reptable component techComp which have image and title
This is the response i get when i hit /api/page?populate=*

The compoents inside comp1 do not get populated.
This is the response when i hit /api/page?populate[block][populate]=*

All the components get populate but not the images inside the nested components.
I just want to populate all the components, nested components, all images.
Is there any way
