render svg file failed

[blessingsi]

I'm trying to render graph to svg file. My code:

func main() {
        ctx := context.Background()
	g, err := graphviz.New(ctx)
	if err != nil {
		panic(err)
	}

	graph, err := g.Graph()
	if err != nil {
		panic(err)
	}

	n1, _ := graph.CreateNodeByName("xx")
	n2, _ := graph.CreateNodeByName("yy")
	graph.CreateEdgeByName("e1", n1, n2)

	if err := g.RenderFilename(ctx, graph, graphviz.SVG, "test.svg"); err != nil {
		panic(err)
	}
}

I got an error: module closed with exit_code(1). It failed when call wasm function, how can I debug this error?

I test this on my Macbook pro and linux server, both failed.

go version
go version go1.23.4 darwin/arm64

go version
go version go1.22.8 linux/amd64

Edit: The following is being observed with goccy/go-graphviz@v0.2.9

I am receiving this same error.

It is occurring when calling RenderFilename

The error is being returned from wazero from a call to the function call in internal/wasm/bind.go

I am running on Debian 12.10.
Linux pm1-lxc-deb08-01 6.8.8-2-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.8-2 (2024-06-24T09:00Z) x86_64 GNU/Linux

go version go1.24.2 linux/amd64

I am able to run the $HOME/go/bin/dot command and render a dot file to SVG using.

Please advise.

I have the same error, too (I use MacOS). Same error on both SVG and DOT formats. Do not know the reason, but I know how to get around the error.

Use g.Render instead of g.RenderFilename. For instance:

file, err := os.OpenFile("/path/to/file.svg", os.O_RDWR|os.O_CREATE|os.O_TRUNC, 0666)
if err != nil {
	panic(err)
}
defer func() {
	if err := file.Close(); err != nil {
		panic(err)
	}
}()

if err := g.Render(context.Background(), graph, graphviz.SVG, file); err != nil {
	panic(err)
}

This might be related to #112, can someone verify if #116 would resolve this issue too?
