Unable to execute multiple include query in loopback

[pavanchandanam]

let marketingprograms: any = await this.marketingProgramRepository.find({
include: {
relation: 'Brand', // include the brand model
scope: { // further filter the owner object
fields: ['brandName'], // only show one field
include: {
relation: 'Country',
scope: {
fields: ['countryId'],
scope: {
where: { MktngPgmId: marketingProgramId }
}
}
}
}
}
});

it is showing the error on the first include line as

Argument of type '{ include: { relation: string; scope: { fields: string[]; include: { relation: string; scope: { fields: string[]; scope: { where: { MktngPgmId: any; }; }; }; }; }; }; }' is not assignable to parameter of type 'Filter'.
Types of property 'include' are incompatible.
Type '{ relation: string; scope: { fields: string[]; include: { relation: string; scope: { fields: string[]; scope: { where: { MktngPgmId: any; }; }; }; }; }; }' is not assignable to type 'Inclusion[]'.
Object literal may only specify known properties, and 'relation' does not exist in type 'Inclusion[]'.

@jannyHou, could you please take a look? Thanks.

@pavanchandanam The inclusion feature is not supported yet, we are working on retrieving navigational properties incrementally, see epic #1352.

The proposal and implementation stories are explained in #3387

@jannyHou, should we close this as duplicate of #1352?

[jannyHou]

Yeah point it to #1352 is reasonable to me.
Feel free to reopen the issue if you have more questions.
