could this be?
expect(node.codegenNode).toMatchObject({
arguments: [
{
properties: [
{
key: {
content: "modelValue",
isStatic: true
},
value: {
content: "model",
isStatic: false
}
},
{
key: {
content: "onUpdate:modelValue",
isStatic: true
},
value: {
children: [
"$event => (",
{
content: "model",
isStatic: false
},
" = $event)"
]
}
}
]
}
]
});|

Should the error be empty instead of generic malformed?

Yeah, both cases can actually be using the same error. I'll adjust this after merge.
