Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: gittools/actions/gitversion/execute@v1.1.1, gittools/actions/gitversion/setup@v1.1.1. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of parameter 'progress' doesn't match implemented member 'Task<string> IFlickrUpload.ReplacePictureAsync(Stream stream, string fileName, string photoId, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'progress' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'tags' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'description' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'title' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Cannot convert null literal to non-nullable reference type.

Nullability of type of parameter 'context' doesn't match overridden member (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'y' of 'int CreationTimeComparer.Compare(ICacheItem x, ICacheItem y)' doesn't match implicitly implemented member 'int IComparer<ICacheItem>.Compare(ICacheItem? x, ICacheItem? y)' (possibly because of nullability attributes).
