Output for git.master, git.master_jit, rfc.property-hooks
Deprecated: Return type of Event::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /in/sr6cn on line 14 {"id":null,"value":null}
