Could not find accessor for "version"

[dys-bigwig]

Cool project idea, didn't even expect this to exist!

On a new 6.1 64-bit image obtained via Pharo launcher, I opened the playground, pasted the instructions, and chose "Do it". The full error received was 'Could not find accessor for variable named "version"'. I tried the alternative script suggested by someone in the issues (for readability reasons, not due to any errors) and that failed the same way.

I tried on the most recent 8.0 64-bit version just to see if the error was any different, and the code runs without any issue; however it sadly doesn't do anything that I could notice.

Apologies if this was something obvious, or I misunderstood the directions. Cheers.
