Issue with getting SellingPlanPercentagePriceAdjustment

[mehul-infocusp]

I have made query something like this:

											.title()
											.sellingPlanGroups(first: 10) { $0
												.edges { $0
													.node { $0
														.sellingPlans(first: 10) { $0
															.edges { $0
																.node { $0
																	.id()
																	.name()
																	.description()
																	.priceAdjustments { $0
																		.adjustmentValue { $0
																			.onSellingPlanPercentagePriceAdjustment { $0
																				.adjustmentPercentage()
																			}
																		}
																	}
																}
															}
														}
													}
												}
											}

After making call - If I print the values - it shows me the price adjustment values. But when i try to access it via variable - i can get XXX.priceAdjustments.first!.adjustmentValue -> but after that how to read onSellingPlanPercentagePriceAdjustment or adjustmentPercentage is not available. Tried all the possible ways - but unable to access those values.
