Unable to suggest a hotspot due to invalid connection response

So I am working with some hardware that requires connecting to a wifi network before uploading the firmware file. However, I am not seeing any user permission prompt appear and the following error is logged:

2022-12-11 15:20:10.899927-0600 -[2054:22393] [] Failed to send a 9 message to nehelper: <dictionary: 0x213d2e530> { count = 1, transaction: 0, voucher = 0x0, contents = "XPCErrorDescription" => <string: 0x213d2e6c8> { length = 18, contents = "Connection invalid" } } 2022-12-11 15:20:10.899997-0600 -[2054:22393] [] NEHotspotConfigurationHelper failed to communicate to helper server. Hotspot switch failed: Error Domain=NEHotspotConfigurationErrorDomain Code=8 "internal error." UserInfo={NSLocalizedDescription=internal error.}

In short the process is:

• Connect to BLE device
• Tell device a firmware update will occur over wifi
• The device opens a hotspot network (with a configurable SSID/PW)
• The user is expected to connect to the BLE device's hotspot, but I am stuck here
• The firmware update is continued and completed over wifi

My code more or less is:

import NetworkExtension
// ...
                NEHotspotConfigurationManager.shared.removeConfiguration(forSSID: deviceSerialNumber)
                
                let wifiConfig = NEHotspotConfiguration(ssid: deviceSerialNumber, passphrase: deviceSerialNumber, isWEP: false)
                // Not setting joinOnce or setting it to true does not change the bahavior
                wifiConfig.joinOnce = false
                wifiConfig.lifeTimeInDays = 1
                // Using a background thread did not change the behavior
                DispatchQueue.main.async {
                    NEHotspotConfigurationManager.shared.apply(wifiConfig) { error in
                        if (error != nil)
                        {
                            let alreadyConnected: Bool = (error! as NSError).domain == NEHotspotConfigurationErrorDomain && (error! as NSError).code == NEHotspotConfigurationError.alreadyAssociated.rawValue
                            if (!alreadyConnected)
                            {
                                AppLogger.log("Hotspot switch failed: \(error!)")
                                DispatchQueue.global(qos: .userInitiated).async {
                                    // ...
                                }
                                return
                            }
                        }
                        
                        DispatchQueue.global(qos: .userInitiated).async {
                            // ...
                        }
                    }
                }
// ...

I currently have the following capabilities defined via an imported provisioning file:

• Access WiFi Information
• Hotspot Configuration
• In-App Purchase
• Keychain Sharing
• Media Device Discovery
• Network Extensions
• Wireless Accessory Configuration

Hardware tested on:

• Mac Mini M1 - MacOS Monterey 12.6
• iPhone X - iOS 15.7.1, same result with a different memory address for XPCError

I am very new to Apple development, so I'm probably missing something simple. Any advice will be appreciated.

Thank You!
