Failed to decode data from network.

Hello, I'm trying to setup the Support SDK for an iOS project (Objective-C). When trying to open the help centre a loading bar is shown but stops around 70% and never finishes.

I've tried replicating it by creating a test project with a similar setup but everything is working fine there, so something in the project's environment is disrupting the SDK.

Zendesk SDK:

pod 'ZendeskSupportSDK', "7.0.0"

Initialisation:

[ZDKClassicCoreLogger setEnabled:YES];
[ZDKClassicCoreLogger setLogLevel:ZDKClassicLogLevelVerbose];

[ZDKClassicZendesk initializeWithAppId:XXXXXXXX clientId:XXXXXXXX zendeskUrl:XXXXXXXX];

id<ZDKObjCIdentity> userIdentity = [[ZDKObjCAnonymous alloc] initWithName:nil email:nil];

[[ZDKClassicZendesk instance] setIdentity:userIdentity];

[ZDKSupport initializeWithZendesk: [ZDKClassicZendesk instance]];

Opening the Help Center:

// controller is the current UIViewController.

UIViewController *helpCenter = [ZDKHelpCenterUi buildHelpCenterOverviewUiWithConfigs:@[]];

UINavigationController *navigationController = [[UINavigationController alloc] init];
[navigationController pushViewController:helpCenter animated:YES ];

[controller presentViewController:navigationController animated:YES completion:nil];
