Thanks for this!
I noticed that all the chords with '#' char are wrong.
Ah yes - you're totally right! (I had a feeling there would be some issue 😄 ), and there were two:
1 -- I forgot to url encode the chordnames, which meant that it was interpreting A#7 as just A - since the # is interpreted in urls as the page anchor.
2 -- the "strangeness" I had pointed out w/r/t Abdim, Gdim and Gbdim was because the fingerings it was returning were in frets higher than 9. ie. x 11 12 13 12 x - which your original code isn't set up to handle.
So once again, I manually added the fingerings lower down on the fret board.
Here is the output

Note: the API returned weird 12 string values for
Abdim,GdimandGbdim- so I changed them manually -- but here's the result:
