your problem here:

constructor(private modal: ngbmodal,     private iintern: iintern, private ievent: ievent,     private internservice: internservice,     private toastr: toastrservice,     private router: router,     private authservice: authservice,     @inject(document) doc: any) { } 

remove following constructor private iintern: iintern, private ievent: ievent , @inject(document) doc: any, i'm not entirely sure doc being used for?

the line see being used removed items private ievent: ievent. if require these used varibales, add them top of component so:

export class analysiscomponent implements oninit {   public event: ievent;   public intern: iintern;   public doc: document; 

your constructor should this:

constructor(private modal: ngbmodal,     private internservice: internservice,     private toastr: toastrservice,     private router: router,     private authservice: authservice) { }
