Description of problem¶

NFS exports are failing sometime with below mentioned error.

API ERROR:
NoneType' object is not subscriptable

Console Error:

2forms.mjs:5855
It looks like you're using the disabled attribute with a reactive form directive. If you set disabled to true
when you set up this control in your component class, the disabled attribute will actually be set in the DOM for
you. We recommend using this approach to avoid 'changed after checked' errors.

Example:
  form = new FormGroup({
    first: new FormControl({value: 'Nancy', disabled: true}, Validators.required),
    last: new FormControl('Drew', Validators.required)
  });
