Short description of error
Baking a texture always turns out black, when using Principled BSDF shader with Metallic setting used
without Metallic it works fine
Exact steps for others to reproduce the error
I attach a file, but you may have to replace the texture
also I attach two images, with one showing bug and one working{F8869290}
I already had problems trying to bake stuff too, usually I have to put the texture in a diffuse BSDF in order for it to work, also I think its not only with metalic on that it stops working: https://blender.stackexchange.com/questions/95328/cycles-baking-diffuse-result-is-always-black, but I don't know if it is a know issue/limitation of baking.
This is correct. See https://docs.blender.org/manual/en/dev/render/shader_nodes/shader/principled.html#inputs and https://docs.blender.org/manual/en/dev/render/cycles/baking.html#bake-types
You can look at diffuse color pass and tweak metallic property and see that it goes to pure black.
