I have UserID: number in my user.model.ts file and i have function to reset my form in user.component.ts. `

resetForm(form?: NgForm) {
    if(form!=null)
    form.resetForm();
    this.service.formData = {
      UserID : null,
      UserName: '',
      Password: '',
      confirmPass: '',
      FirstName: '',

      UserRole: ''
    }
  }

CodePudding user response：

if you don't want to hustle with such errors u can set "strictNullChecks": false, in the compilerOptions in your tsconfig.json

CodePudding user response：

Try changing the type of userId to

userID?: number;

or to

userID: null | number;

in your service
