Dynamic ref path does not work inside Map

[ManimuthurajT]

I have schema type as Map in my mongoose model.
How to use refPath in Map? using "values.$*.refp" doesn't work.
This is my model:

const listFieldValuesSchemaDef = {
    ...
    value: {
        type: Schema.Types.Mixed,
    },
    valueObject: {
        type: Schema.Types.ObjectId,
        refPath: "values.$*.refp",
    },
    refp: {
        type: Schema.Types.String,
    },
};

const listRowSchemaDef = {
    ...
    values: { type: Schema.Types.Map, of: listFieldValuesSchema },
};
