Trouble while baking texture

I got this tentacle with procedural material



I try bake this color but only black color show on baked texture image
I used defualt settings

For diffuse colour I would use these settings:

Why don’t you have a New Texture Image in your Node Tree selected but not connected to anything?
You Need a new initialized Image texture for all the things you are using…Diffuse, Roughness Normal Maps, etc.

Did you UNwrap your Mesh? You need a UV also…
