Nullability in constraints for type parameter 'TState' of method 'ColorConsoleLogger.BeginScope<TState>(TState)' doesn't match the constraints for type parameter 'TState' of interface method 'ILogger.BeginScope<TState>(TState)'. Consider using an explicit interface implementation instead.

Nullability of reference types in type of parameter 'schema' of 'Task<JObject> AngleSharpContentParser.ParseAsync(string html, Schema schema)' doesn't match implicitly implemented member 'Task<JObject> IContentParser.ParseAsync(string html, Schema? schema)' (possibly because of nullability attributes).

Non-nullable property 'PostProcessor' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable property 'ScraperConfigStorage' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Non-nullable event 'ScrapedData' must contain a non-null value when exiting constructor. Consider declaring the event as nullable.

Dereference of a possibly null reference.

Dereference of a possibly null reference.

Possible null reference argument for parameter 'scraperConfigStorage' in 'SpiderBuilder SpiderBuilder.WithConfigStorage(IScraperConfigStorage scraperConfigStorage)'.

Non-nullable field '_startUrls' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.
