I'm trying to use latest Ishikawa diagram in silverbullet bit needs v11.12.3+
So I just tried to update the plug in Library/silverbullet-mermaid as below (11.16.0 is the latest release)
In general, if these kinds of things don't work, it often helps to take a look at the browser developer tools and then the console. With silverbullet there often is an error there, that might help. (Although they are often cryptic.)
I think the problem with your configuration is that there is no comma on the end of line "integrity_disabled = true". That makes lua confused about the whole configuration section (which means it basically ignores the configuration section and adds an error in the developer tools console.) I think if the comma was there, it probably would work.
The 'integrity = ' line doesn't contain a correct hash, but if you disable the integrity that line is ignored.
By the way, this is my configuration, which was able to draw your ishikawa diagram:
config.set("mermaid", {
version = "11.16.0",
integrity = "sha256-dNfEbavKMowilHM5EKiqHtDDdFF3bo1Sldo4ordY+5s=",
})
