Displaying shader error in console

Questions
#1

I am following the Three Js journey course and in the example using ShaderMaterial, when there is an error in the vertexShader program, the console outputs all the lines of code in the console like the following:

But my console does not display all the lines, it simply states the error:

I was wondering how I can make Three Js show me all the lines of code when there is an error?

#2

I believe older versions of the library printed everything, now it prints just a snippet.

You can modify the library code to print all shaders before they are compiled or in case of an error.
