blender 2.8 uploading rigged avatar problem

[konebii]

i have just downloaded blender 2.8

i created an avatar and used basic human meta rig  armature for rigging. i think thats the default armature for blender 2.8

i did everythnig -x thing and other stuff for exporting as collada.

when i try to upload rigged mesh into second life, include skin weight is  greyed out. so i cant upload rigged avatar into second life. 
what may i be doing wrong?

You can't create your own skeleton when creating rigged mesh for SL. You have to use the official skeleton.
