"'Symbol()' not found injection error in Vuejs"

Question

I am using confirmdialog in primevue and encountered the following error:

[Vue Warning]: Injection "Symbol()" not found

I have no idea what this error means or how to fix it. Can anyone please help me? Here is my source code:

const deleteCategory = () => {
        confirm.require({
            message: 'Are you sure you want to continue? ',
            header: 'confirm',
            icon: 'pi pi-exclamation-triangle',
            accept: () => {
               notification.showMessage("Success!");
            },
            reject: () => {
              router.push({ name: "CategoriesPage" });
            }
        });
    }

Error[Vue warn]: injection "Symbol()" not foundHas nothing to do with the code you provided. When using inject: ['injectedVar'] in a nested component, if it is not provided from the parent component, [Vue warn]: injection ... not found will appear.

So you should check what you are trying to inject and where it needs to be served from. For more information, see the documentation: Provide/Inject
