The code is throwing an error: Unable to access the 'grower' property as it is undefined

I'm facing an issue with a button that triggers the function 'SaveNewOpportunity' in my component file. When I click the button, I encounter the following error:

ERROR TypeError: Cannot read property 'grower' of undefined

Here is the HTML code for the button:

  <button
   mat-flat-button
   color="accent"
   (click)="saveNewOpportunity()"
   [disabled]="isEdit">
   Save </button>

And here is the corresponding Typescript code:

saveNewOpportunity() {
    // Function logic here
}

Despite reviewing the code, I'm unable to identify the source of the error. The browser console displays the following message:

OpportunityComponent.html:734 ERROR TypeError: Cannot read property 'grower' of undefined
at OpportunityComponent.push../src/app/layout/opportunity/opportunity.component.ts.OpportunityComponent.saveNewOpportunity (opportunity.component.ts:772)
at Object.eval [as handleEvent] (OpportunityComponent.html:737)
at handleEvent (core.js:21652)

Answer №1

Following the advice from @OleksiiMiroshnyk, I made a modification to my code:

thresholdGroups: ThresholdGroups = new ThresholdGroups()

This adjustment proved effective, even though the original code was functional at first. It's unclear what caused the change, but creating an instance of the object as recommended by OleksiiMiroshnyk resolved the issue.
