I have just tried this several times and spent two days trying to figure out how to do this. I even contacted adobe about this and their support said it cannot be done. Out of frustration i kept trying many things. I decided to close out both indesign and illustrator. Created new files etc. Still no avail. I then copied the gradient object from illustrator and went into indesign and selected edit menu then "paste into place". it worked!
