Well, it looks like for the second error thick has not been defined.  And
I would guess (although I don't know for sure, because there's not enough
code shown in your mail) that width is not defined in the first case.

I tried the snippet from the referenced thread, and it works if you comment out

\once \override ChordName #'stencil = \percentStencil

Otherwise, as Carl says, 'thickness and 'slope are undefined: these are properties of RepeatSlash, not of ChordName. (This suggestion is of course not ideal, but the function will work with the override if you hardcode values for these properties.)

HTH,
