Workload Versions

We identified a regression in automatic breadcrumb collection after updating the SDK.

SDK Version 6.6.0: Automatic breadcrumbs are captured and attached to events properly. ✅

SDK Version 6.11.0: Automatic breadcrumbs are entirely missing from captured events. ❌

Environment / Context:

Platform: .NET MAUI / iOS

Package: Sentry.Maui v6.11.0

Expected Behavior:
Automatic breadcrumbs (lifecycle events, UI events, system logs) should be collected and included in events, matching the behavior observed in v6.6.0.

Actual Behavior:
No automatic breadcrumbs are attached to events sent from clients running v6.11.0.

UseSentry or SentrySdk.Init call

SentrySdk.CaptureException(exception)

Steps to Reproduce

Configure Sentry.Maui with options targeting v6.6.0 and trigger an event -> Breadcrumbs are present.

Upgrade Sentry.Maui to v6.11.0 and trigger an event -> Breadcrumbs array is empty/missing.

Expected Result

Breadcrumbs on

Actual Result

Breadcrumbs off

    @fototop I'm not able to reproduce this and I can't think of any changes we've made in the managed SDK that would explain this.

    1. Which events are missing breadcrumbs? Managed CaptureException events, or native crashes?
    2. What options are you using to initialise Sentry? In particular anything you're doing with SetBeforeBreadcrumb, MaxBreadcrumbs, EnableAutoBreadcrumbTracking or EnableSwizzling.
    3. Does it happen on 6.9.0, and on 6.10.0 or just 6.11.0?

    If you could provide a minimal reproduction of the issue describing clearly what you see on version X and what you expect to see (but aren't seeing) on version Y, we can look into it further.

    Also, are you really seeing this on all operating systems? Would be good to know which OS you noticed it on (Android, iOS etc.). Make sure to include that information in the repro instructions.

    👋 Thanks for the report! We've added the Needs Reproduction label because we need a minimal reproduction to investigate further.

    Please provide a link to a public GitHub repository that reproduces the issue with as little code as possible. Our repro guide has tips on how to create one.

    Some quick hints:

    • Start from a fresh dotnet new console (or similar) project
    • Add only the Sentry NuGet package(s) relevant to the bug
    • Include the exact SDK version number and your SentrySdk.Init / UseSentry call (with the DSN blanked out)

    Alternatively, if the issue only manifests in your own codebase, you could try gradually removing code until you have a minimal repro.
