I have an object model that has an array as one of its values. I'm trying to populate it but I get an error in my VS Code environment:

Type 'Promise' is missing the following properties from type 'GenericViewModel': rating, reportingDate, comments, and 4 more.ts(2740)

I have searched and can't determine how to populate the property correctly. Everything I have seen online says that this is the correct way. I am using Visual Studio Code and building an Angular application.

My function and model are as follows:

async getRawData(){
   let pList: PViewModel[] = [];
   let criteria = {storedProcedure: 'sp_Get_Data_For_ESM'};
   await super.post(
            'universal-sp-pass-thru/spPassThroughnoBody',
            criteria,
            'api-eprs'
        ); //this runs the sql
   pList = this.apiPostResponse.data;
   const scorecardData: ScorecardModel = {pcorecardModel: []};

         // Process each 
   pList.forEach((p) => {
        const pData: PScorecardModel = {
            pId: p.pId,           
            OpenViewModel: [],
        };


    // Populate the specific view model list (example for ENG_STAFFING_3_LA)
    // Replace `new Date()` with the actual reporting date if it is available.
    pData.OpenViewModel[] = this.getGenericData(p.pId, p.reportingDate,p.OpenViewModel_ST,p.OpenViewModel_TABLE)

    // Append the populated program data to the scorecard
    scorecardData.pScorecardModel.push(pData);
  });

async getGenericData(pId:string,reportingDate:Date | null, ised:string,    tablename:string): Promise {

   let GenericViewModel: GenericViewModel[] = [];
   let body = {
       pId: pId,
       reportingDate:reportingDate,
       ised: ised,
       tablename: tablename,
    };
    let criteria = {
       storedProcedure: 'sp_GetScorecard',
       body: body,
    };
    await super.post(
       'sword-universal-sp-pass-thru/spPassThrough',
       criteria,
       'api-eprs'
    ); //this runs the sql
    GenericViewModel = this.apiPostResponse.data; /

    return GenericViewModel;
}

/** Generic view‑model used in many collections */
export interface GenericViewModel {
    rating: string;
    reportingDate: Date | null;
    comments: string;
    results: string;
    rtg_date: string;
    phase: string;
    denominator: number;
}
export interface ProgramScorecardModel {
    pId: string;    
    OpenViewModel: GenericViewModel[];    
}

I get the error on this line:

pData.OpenViewModel[] = this.getGenericData(p.pId, p.reportingDate,p.OpenViewModel_ST,p.OpenViewModel_TABLE)

How do I properly populate the pData.OpenViewModel[]?
