Bug: interface is missing optional hostname

[Infern1]

Describe the bug Compiler complains Property 'hostname' does not exist on type 'IMeta'. However it does exist, maybe not in all cases.

To Reproduce Try to access the logObj

Expected behavior Interface is extended with all parameters, something like:

export interface IMeta extends IMetaStatic {
  date: Date;
  logLevelId: number;
  logLevelName: string;
  hostname?: string;
  path?: IStackFrame;
}
