An issue occurred during the construction of an angular project: The Tuple type '[]' with a length of '0' does not contain any elements at index '0'

When I run the command ng build --prod, I encounter the following error:

ERROR in src/app/inventory/inv-parts-main-table/dialog-component/dialog-component.component.html(5,16): Tuple type '[]' of length '0' has no element at index '0'.

Source code related to the error is as follows

<div mat-dialog-content>
    <div style="margin-top: 30pt" *ngIf="data.quote[0]!=null">
      <span><b>{{data.quote[0] | currency}}</b></span> <br />
      {{data.lastUpdatedDate[0] | date :'mediumDate'}} | {{data.supplierName[0]}}
    </div>
    <div style="margin-top: 10pt" *ngIf="data.quote[1]!=null">
      <span><b>{{data.quote[1] | currency}}</b></span> <br />
      {{data.lastUpdatedDate[1] | date :'mediumDate'}} | {{data.supplierName[1]}}
    </div>
    <div style="margin-top: 10pt" *ngIf="data.quote[2]!=null">
      <span><b>{{data.quote[2] | currency}}</b></span> <br />
      {{data.lastUpdatedDate[2] | date :'mediumDate'}} | {{data.supplierName[2]}}
    </div>
</div>

The Typescript (.ts) file structure is shown below

export interface DialogData {
  quote: [];
  lastUpdatedDate : [];
  supplierName: [];
}

Answer №1

I was able to resolve the problem by making the following adjustment

The tuple type '[]' with a length of '0' does not have an element at index '1'.

export interface DialogData {
  quote: string[];
  lastUpdatedDate : string[];
  supplierName: string[];
}
