Spontaneous Crash on iOS with DelegatingHandler

[michalhoblik]

Hi,

we are getting spontaneous crashes on iOS if we are using our custom DelegatingHandler. Sometimes the app is working for couple of minutes/api calls without crash and then it crashes. There is not relevant exception for this, just a SIGABRT Crash from iOS. If we hard-code our api key in the delegatinghandler, the app is working fine. Is there some misconfiguration on our side? Or is there better way to do this? Thanks.

Versions: Maui: 8.0.40 (happens in every Maui 8> version) Apizr: 5.4.0 Shiny.Framework: 4.1.0 Prism.DryIoc.Maui: 9.0.401-pre

Registration in Maui:

builder.Services.AddApizr(apizrRegistry => apizrRegistry .AddManagerFor<IImpressumApi>() apizrExtendedCommonOptionsBuilder => apizrExtendedCommonOptionsBuilder .WithBaseAddress(builder.Configuration.GetValue<Uri>("BaseUrl")) .AddDelegatingHandler((provider) => new XApiKeyAuthenticationHandler(provider.GetRequiredService<ISecureStorage>())) .WithAkavacheCacheHandler() .WithExCatching(OnException, letThrowOnExceptionWithEmptyCache: false) .WithLogging( #if DEBUG HttpTracerMode.Everything, HttpMessageParts.All, LogLevel.Trace, LogLevel.Information, LogLevel.Critical #else HttpTracerMode.ExceptionsOnly, HttpMessageParts.ResponseAll, Microsoft.Extensions.Logging.LogLevel.Trace, Microsoft.Extensions.Logging.LogLevel.Information, Microsoft.Extensions.Logging.LogLevel.Critical #endif ) .WithConnectivityHandler<IConnectivity>(connectivity => connectivity.NetworkAccess == NetworkAccess.Internet));

DelegatingHandler:

`public class XApiKeyAuthenticationHandler : DelegatingHandler { public XApiKeyAuthenticationHandler(ISecureStorage secureStorage) : this(secureStorage, new HttpClientHandler()) { }

public XApiKeyAuthenticationHandler(ISecureStorage secureStorage, HttpMessageHandler innerHandler)  : base(innerHandler)
{
    SecureStorage = secureStorage;
}

protected ISecureStorage SecureStorage { get; }

protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request,
    CancellationToken cancellationToken)
{
    var identityKey = await SecureStorage.GetAsync(AppConstants.IdentityKey);
    if (!string.IsNullOrWhiteSpace(identityKey))
    {
        request.Headers.Add("X-Identity-Key", identityKey);
    }

    return await base.SendAsync(request, cancellationToken);
}

}`
