  }
}

"vars" must be the last part of the key

vars.d2-config.layout-engine: elk

a

"vars" must be the last part of the key

this message causes more confusion.

foo.vars: {
  bar
}

I have the same issue. Trying to use the Go API oracle to set vars but getting this error.

[alixander]

it's not allowed because i don't want to give the impression this is allowed

vars: {
  a: 1
}

x1: ${a}

vars.a: 2

x1: ${a}

these will both be 2. As d2 is a declarative language, variable reassignment is not a feature.
