Most of the angular developer face the above problem when they are dealing with Reactive forms
"Must supply a value for form control with name /......"
this is because we donot provide the all field value that are in the reactive form and we are using the setValue method in angular.
this problem can be solved by two ways.
1. you can provide the value of all form control that you are using with reactive form.
2. or in your's case you want to provide the value for the some set of formcontrol then instead of using setValue() we can use patchValue() for loading the data
