Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of MyError::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/b9g9h on line 15 {"name":"Page not found","code":404,"msg":"Unfortunately, the page does not exist"}
