Sonarlint: Provide the parametrised type for this generic

Question

I have installed an extension called sonarlint, I am trying to refactor my code and reduce code smells, the plugin is suggesting I do further modifications like

Raw types should not be used Code smell Generic types shouldn’t be used raw (without type parameters) in variable declarations or return values. Doing so bypasses generic type checking, and defers the catch of unsafe code to runtime.

This is one example where it complains

public ResponseWrapper update(TerritoryDto territoryDto) throws IOException {
    // Validate the payload
    var validationResponse = validateUpdatePayload(territoryDto);
    if (validationResponse.getCode() != HttpStatus.OK.value()) return validationResponse;
    TerritoryEntity territory = (TerritoryEntity) validationResponse.getData();

    territory.setPolygon(territoryDto.getPolygon());
    var updated = territoryRepository.save(territory);
    var erpResponse = territoryErpClient.updateTerritory(
        new UpdateTerritoryBoundary(territory.getPolygon().toString()),
        territory.getName()
    );
    if (erpResponse == null) {
        // todo - Consider sending notifications to slack about ERPNext not being reachable.
    }
    return ResponseWrapper
        .builder()
        .code(HttpStatus.OK.value())
        .message("Territory updated successfully")
        .data(TerritoryConverterInterface.TerritoryEntityToDtoMapper.INSTANCE.converter(updated))
        .build();
}

I tried to make modifications according to the sonarLint alert but it is not working. Please help me with this problem. Thank you all.
