Sonarlint: Provide the parametrised type for this generic

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

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.
