Thrown here https://github.com/DSharpPlus/DSharpPlus/blob/5387f0a240956d0bee74213cddaaaf88a04f0381/DSharpPlus/Entities/AuditLogs/AuditLogParser.cs#L1090-L1097 `auditLogAction.TargetId!.Value` does contain the channel ID, but the `GetChannel()` call returns null so attempting to access `PermissionOverwrites` throws an NRE\n\n### What version of the library are you using?\n\nv5.0.0-nightly (make sure you are using the latest nightly!)\n\n### What .NET version are you using? Make sure to use the latest patch release for your major version.\n\n.NET 9.0\n\n### Operating System\n\n_No response_\n\n### Reproduction Steps\n\n1. Create a Discord channel\n2. Make any change to its permissions (create a user/role override, delete an override, change permissions for a user/role or the everyone role... doesn't matter)\n3. Delete the channel\n4. Attempt to fetch any number of Audit Log entries, including the second-last one (which will be your permission update), and call `ToListAsync()`—so at least something like `await Guild.GetAuditLogsAsync(2).ToListAsync()`\n\n### Trace Logs\n\n```log\n[2025-11-26 19:27:42 +00:00] [DSharpPlus.Net.RestClient] [Trace] Request 01KB0T5JEPFB4W10PEF5QXHJKD: {\"audit_log_entries\":[{\"id\":\"1443321070076559521\",\"action_type\":12,\"user_id\":\"455432936339144705\",\"target_id\":\"1443320928946753628\",\"changes\":[{\"key\":\"name\",\"old_value\":\"test\"},{\"key\":\"type\",\"old_value\":0},{\"key\":\"permission_overwrites\",\"old_value\":[]},{\"key\":\"nsfw\",\"old_value\":false},{\"key\":\"rate_limit_per_user\",\"old_value\":0},{\"key\":\"flags\",\"old_value\":0}]},{\"id\":\"1443321057103708324\",\"action_type\":15,\"user_id\":\"455432936339144705\",\"target_id\":\"1443320928946753628\",\"changes\":[{\"key\":\"id\",\"old_value\":\"943672126873960508\"},{\"key\":\"type\",\"old_value\":0},{\"key\":\"allow\",\"old_value\":\"0\"},{\"key\":\"deny\",\"old_value\":\"0\"}],\"options\":{\"id\":\"943672126873960508\",\"role_name\":\"milk\",\"type\":\"0\"}}],\"users\":[{\"id\":\"455432936339144705\",\"username\":\"floatingmilkshake\",\"avatar\":\"bdcbbabbee22ff51c15ade8fdcc98d42\",\"discriminator\":\"0\",\"public_flags\":4194560,\"flags\":4194560,\"banner\":null,\"accent_color\":null,\"global_name\":\"FloatingMilkshake\",\"avatar_decoration_data\":null,\"collectibles\":null,\"display_name_styles\":null,\"banner_color\":null,\"clan\":null,\"primary_guild\":null}],\"integrations\":[],\"webhooks\":[],\"guild_scheduled_events\":[],\"threads\":[],\"application_commands\":[],\"auto_moderation_rules\":[]}\n```\n\n### Exceptions or other error messages\n\n```txt\nAn unexpected error occurred: Object reference not set to an instance of an object.\n   at DSharpPlus.Entities.AuditLogs.AuditLogParser.ParseOverwriteEntry(DiscordGuild guild, AuditLogAction auditLogAction) in /home/milkshake/repos/DSharpPlus/DSharpPlus/Entities/AuditLogs/AuditLogParser.cs:line 1090\n   at DSharpPlus.Entities.AuditLogs.AuditLogParser.ParseAuditLogEntryAsync(DiscordGuild guild, AuditLogAction auditLogAction, IDictionary`2 members, IDictionary`2 threads, IDictionary`2 webhooks, IDictionary`2 events) in /home/milkshake/repos/DSharpPlus/DSharpPlus/Entities/AuditLogs/AuditLogParser.cs:line 162\n   at DSharpPlus.Entities.AuditLogs.AuditLogParser.ParseAuditLogToEntriesAsync(DiscordGuild guild, AuditLog auditLog, CancellationToken cancellationToken)+MoveNext() in /home/milkshake/repos/DSharpPlus/DSharpPlus/Entities/AuditLogs/AuditLogParser.cs:line 102\n   at DSharpPlus.Entities.AuditLogs.AuditLogParser.ParseAuditLogToEntriesAsync(DiscordGuild guild, AuditLog auditLog, CancellationToken cancellationToken)+System.Threading.Tasks.Sources.IValueTaskSource\u003cSystem.Boolean\u003e.GetResult()\n   at DSharpPlus.Entities.DiscordGuild.GetAuditLogsAsync(Nullable`1 limit, DiscordMember byMember, Nullable`1 actionType)+MoveNext() in /home/milkshake/repos/DSharpPlus/DSharpPlus/Entities/Guild/DiscordGuild.cs:line 2001\n   at DSharpPlus.Entities.DiscordGuild.GetAuditLogsAsync(Nullable`1 limit, DiscordMember byMember, Nullable`1 actionType)+MoveNext() in /home/milkshake/repos/DSharpPlus/DSharpPlus/Entities/Guild/DiscordGuild.cs:line 2001\n   at DSharpPlus.Entities.DiscordGuild.GetAuditLogsAsync(Nullable`1 limit, DiscordMember byMember, Nullable`1 actionType)+System.Threading.Tasks.Sources.IValueTaskSource\u003cSystem.Boolean\u003e.GetResult()\n   at System.Linq.AsyncEnumerable.\u003cToListAsync\u003eg__Core|424_0[TSource](IAsyncEnumerable`1 source, CancellationToken cancellationToken) in /_/Ix.NET/Source/System.Linq.Async/System/Linq/Operators/ToList.cs:line 36\n   at System.Linq.AsyncEnumerable.\u003cToListAsync\u003eg__Core|424_0[TSource](IAsyncEnumerable`1 source, CancellationToken cancellationToken) in /_/Ix.NET/Source/System.Linq.Async/System/Linq/Operators/ToList.cs:line 36\n```\n\n### Anything else you'd like to share\n\n_No response_","author":{"url":"https://github.com/FloatingMilkshake","@type":"Person","name":"FloatingMilkshake"},"datePublished":"2025-11-26T19:57:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2396/DSharpPlus/issues/2396"}
