Character and animation import Error(UE4.15)

Greetings all.
first i have to let you guys know that I’m still at Amateur level in using unreal, I did try to look for guides\docs\answerhub and I haven’t found any similar post about this error, so either I don’t know some basics in importing characters or this is a new kind of error.
and the problem is this, I have that character that I built all by myself, did some animation and i want to import it to the project.
when i’m importing the character itself i get this massage:

BUT, the character looks to get imported with no real issues

but then when I ty to import the animation i get this:

and the imports fails.

I’m using Maya2017
this is was basically my workflow:
in importing the character i made sure to separete the mesh from the skeleton, and made sure the the import completed with no errors from Maya.
also i made sure the the rig didn’t have any controllers - as from what i gather, Unreal cant “read” controllers
I have made sure that after sepereting the controllers from the rig that the animation is working smoothly and I also used “Bake Animation” before importing
and i did export the character and the animation as separate files (FBX2014 of course)
please let me know what I’m missing here for it to work

What program do you use for 3D modeling?

Maya 2017
