Full Shader File which is failing to compile

Shader in unity webgl build is failing to compile and object becomes invisible in game
i found few resources with solution of replacing all ternary operators with if else 
it worked and mesh/object was visible again but shader was still giving console error.

Submitter: we don't have a way to translate this shader into something executable in WebGL so I doubt we'll be able to triage your report. A self-contained test case is needed.

I will be soon uploading a self contained test case sorry for late reply
