FBX file from Blender not uploading to Mixamo

Every time I export an FBX file from Blender (version [your version number]) and upload it to Mixamo, the site fails to process the file.
OBJ works fine, but FBX gives an error. The same FBX imports correctly in Blender and Unreal, so it’s not corrupted.
Please look into this issue or update the documentation with supported Blender FBX export settings.
