We are using unity addressables that generate bundle files with .bundle extension. So when we tried to add assetPack with that extension, we got error InvalidBundleName.
So we found a workaround, where we directly add to AssetPacks in AssetPackConfig:

config.AssetPacks.Add(addressableGroupBase.BundleName, new AssetPack()
				{
					AssetBundleFilePath = addressableGroupBase.FilePath,
					DeliveryMode = addressableGroupBase.InstallTimeDelivery ? AssetPackDeliveryMode.InstallTime : AssetPackDeliveryMode.OnDemand
				});

This worked just fine until we updated AssetDelivery from 1.4.0 to 1.5.0. Then, after running BundleTool, Unity builds entire game and at the very end it gets exception InvalidBundleName - asset pack name "PATH_TO_BUNDLE" is invalid.
