TSLint throws an error, expecting either an assignment or function call

While running tslint on my angular project, I encountered an error that I am having trouble understanding. The error message is: expected an assignment or function call

getInfoPrinting() {
this.imprimirService.getInfoPrinting().subscribe(
  response => {
    this.loading = false;
    this.printingOrders = response.data;
    this.totalNumberOfCharacters = 0;
    this.totalNumberOfCharactersNext = 0;
    if (this.printingOrders.labelPresentOrder && this.printingOrders.labelPresentOrder.lines) {
      this.printingOrders.labelPresentOrder.lines.forEach(
        line => {
          this.totalNumberOfCharacters += line.length;
        }
      );
    }
    if (this.printingOrders.labelNextOrder && this.printingOrders.labelNextOrder.lines) {
      this.printingOrders.labelNextOrder.lines.forEach(
        line => {
          this.totalNumberOfCharactersNext += line.length;
        }
      );
    }
    if (this.printingOrders.printing) {
      this.suscribeNotifications();
    }
  }
), err => {
  this.loading = false;
  this.alertService.error(INFO_NO_EXISTEN_ORDEN_PREPARADA);
  this.hasAlert = true;
};

}

The line causing the error is:

this.imprimirService.getInfoPrinting().subscribe(

Can anyone help me understand what I am doing wrong?

Appreciate your assistance.

Answer №1

Your code needs some adjustments. Instead of

fetchData() {
    this.printService.fetchData().subscribe(
      response => {
        // handle response
      }
    ), err => {
      // handle error
    };
}

You should modify it to

fetchData() {
    this.printService.fetchData().subscribe(
      response => {
        // handle response
      }, 
      err => {
        // handle error
    });
}

To make debugging easier, consider breaking down the callback functions into separate methods.
