[BUG] Error using propDefinition in additionalProps

I'm trying to use `propDefinition` inside `additionalProps()`. I get an error trying to load the additional props when configuring the component in the builder.

```
async additionalProps() {
return {
userIds: {
propDefinition: [
notion,
"userIds"
],
}
};
},
```
