type: () => {
const param = parameterByName(get().getters, g.name, p.name);
// Ensure param is defined before accessing properties
return param?.possibleTypes[param.selectedTypeIdx];
},

originalType: () => {
const param = parameterByName(get().getters, g.name, p.name);
// Ensure param is defined before accessing properties
return param?.possibleTypes[0];
