this._endpointService.getData('/myGet') .then((res:any) => { let blob = new Blob([res.error.text], { type: 'application/pdf' }) var fileURL = URL.createObjectURL(blob); this.tryDoctype = blob
})

Please try below:

//import this ref
this._endpointService.getData('/myGet') .then((res:any) => { //change in response let blob = new Blob([res.error.text.blob()], { type: 'application/pdf' }) let fileURL = URL.createObjectURL(blob); //if you have any error then try this //this.tryDoctype = this.sanitizer.bypassSecurityTrustResourceUrl(fileURL); this.tryDoctype = fileURL;
})

Assign fileURL to Iframe

 <iframe *ngIf="tryDoctype" [src]="tryDoctype" width="950" height="600"></iframe>
