Rigging Issue with Skeleton from Mixamo

Hey Everyone was working on a tunic, for a game I’m wanting to make. I end up using Mixamo to rig the model for the Player. But In the game there is suppose to be tunics you can buy your character, I tried rigging it to the same skeleton as the model use in Mixamo .And I keep getting this :

"FAILED TO MERGE BONES:

This could happen if significant hierarchical changes have been made
e.g. inserting a bone between nodes.
Would you like to regenerate the Skeleton from this mesh?

WARNING: THIS MAY INVALIDATE OR REQUIRE RECOMPRESSION OF ANIMATION DATA.
"

Anyone have any Idea how to et this bones to match, for they are same skeleton, but for some odd reason I keep getting this. If anyone has been through this before please give me a pointer about what to do. Thank you,

when you import the animation, import the skeleton too. Then retarget the animation to your character

If a Skeletal Mesh is already associated with a Skeleton asset in Unreal and you import another Skeletal Mesh with a different Skeletal setup, you may need to perform some Retargeting. Although this is from an earlier version of Unreal, the information in this video series is still relevant if you want to check it out: https://www.youtube.com/playlist?lis…w42fZ1t8dDClsI

Same error

I tried to use two different fbx models as a ue mannequin, but I got an error every time: FAILED TO MERGE BONES:

WARNING: THIS MAY INVALIDATE OR REQUIRE RECOMPRESSION OF ANIMATION DATA. I really don’t know what to do anymore since I’ve tried a bunch of models and reviewed a lot of tutorials and nothing helped me. Due to this error, the animation of running from the ue stage dummy to a custom model is also not retargeted.
