Cannot read property 'graphvizVersion' of undefined

See original GitHub issue

Hello! I contribute to a VS Code extension that uses d3-graphviz for one of its features. While trying to upgrade the dependencies, including d3-graphviz 4.0.0 to 4.1.0, I noticed that the feature broke with the error in the issue title.

I don’t really have experience with the Node ecosystem, so it’s quite likely that I messed something up. Perhaps you might have an idea?

See https://github.com/rust-analyzer/rust-analyzer/pull/11821 for more details. The relevant code is https://github.com/rust-analyzer/rust-analyzer/blob/deb5c14/editors/code/src/commands.ts#L485-L541.

I can now confirm that this is a bug in d3-graphviz. It seems that the new graphvizVersion() does not work when using a web worker. Here’s a workaround:
