sequelize Optional type throws a parsing error

[joshpersaud]

Encore doesn't seem to be able to parse the type Optional in the sequelize package. Models created by sequelize-auto often use this type.

The Object type looks like this:
export type Optional<T,K> = Omit<T, K> & Partial<Pick<T, K>>

Are you sure that's the definition? TypeScript doesn't like that. See https://www.typescriptlang.org/play/?ts=5.7.2#code/KYDwDg9gTgLgBDAnmYcDyYYEsIDsCGANgDwAqANANIB8cAvOgLZYxnlw1wBkcACvrCxFivLAGMA1mw7VqAbgBQQA

Yes positive. You can see the implementation here:
