[0.6.7] Importing classes that imports icon variables

[fguinez]

The problem

I found an issue when importing classes that in turn import icon variables. This fails in 0.6.7, but works in 0.6.6.

The errors only occur when I use imports from c.d2 as icons. I tried changing icon: to label: in b.d2 and it worked. I tried importing everything from a.d2 and it works too, but this doesn't really fit my use case.

I am not sure but maybe it is something related to #2066, because the error message indicates that a remote image has been detected as a local image. But I don't know why this happens with this specific importing structure.

How to replicate

I have the following files in the same directory:

# a.d2 (the file to compile)
...@b.d2

a1: {
    class: Ecs
}

a2: {
    class: Lambda
}

a1 -> a2

# b.d2 (the file with the classes)
...@c.d2

classes: {
    Ecs: {
        shape: "circle"
        icon: ${icons.ecs}
    }

    Lambda: {
        shape: "hexagon"
        icon: ${icons.lambda}
    }
}

# c.d2 (the file with the icons)
vars: {
    icons: {
        ecs: "https://icons.terrastruct.com/aws%2FCompute%2FAmazon-Elastic-Container-Service.svg"
        lambda: "https://icons.terrastruct.com/aws%2FCompute%2FAWS-Lambda.svg"
    }    
}

Depending on the version of D2 that I'm using, the behavior is different.

• With version 0.6.6 I get the following diagram:

• With version 0.6.7 I get the following errors:

Errors
err: failed to bundle .: read .: is a directory
err: failed to compile -: failed to bundle local images: [.]

Set up

• I'm running D2 from VSCode 1.93.1
• D2 VSCode extension v0.8.8
• macOS 15.0.1 (chip M2)
