TypeError: Cannot set property scrollHeight of [object Element] which has only a getter

Question

I am using PrimeNg v11.x element. Application is working fine with scrollHeight value set from a variable but the jasmine test is failing with error:

TypeError: Cannot set property scrollHeight of [object Element] which has only a getter

    <p-tree
        #tree
        [value]="nodes"
        selectionMode="checkbox"
        [scrollHeight]="scrollHeight"
        virtualScroll="true"
        virtualNodeHeight="33"
    ></p-tree>

The test succeeds if i hard code the height value.

Can anyone help how to fix this issue?

Thanks

Try this it may help you. import the module that you are using like TreeModule.

beforeEach(
    waitForAsync(() => {
      TestBed.configureTestingModule({
        imports: [TreeModule],
        declarations: [Componentsdeclaration],
        schemas: [NO_ERRORS_SCHEMA],
      }).compileComponents();
    })
  );
