Error adding a new item to repeatable component

issue: bug severity: medium status: confirmed source: core:strapi

## Bug report ### Describe the bug I am trying to add a new item to a repe…atable component field through an API `PUT /api/[api-name]/:id`. I expected to be able to push a new item on the array without an ID and it will be created, but I receive an error instead. I am not sure if this is a bug or my misunderstanding of the API. ### Steps to reproduce the behavior Example of Lists Content Type <img width="919" alt="Example of Lists Content Type" src="https://user-images.githubusercontent.com/259196/147013877-189f5b91-6287-40a1-ad1e-1456be035ac1.png"> 1. Inside my `beforeUpdate()` lifecycle hook for my `Lists` API, 2. I try to add a new item to my existing `items` array by using: ``` event.params.data.items.push({ title: "Washcloths", checked: true }) ``` 3. I can see it is properly added to the data ``` // event.params.data { title: 'Craigslist', items: [ { title: 'Washcloths', checked: true } ], updatedAt: 2021-12-22T00:21:36.488Z } ``` 4. Then I get the error `error: Invalid id, expected a string or integer, got [object Object]` once it is run ``` Error: Invalid id, expected a string or integer, got [object Object] at node_modules/@strapi/database/lib/entity-manager.js:25:15 ``` ### Expected behavior I would expect it to create a new item for me. ### System - Node.js version: v16.13.0 - NPM version: 8.1.0 - Strapi version: 4.0.0 - Database: sqlite3 - Operating system: Mac OS Monterrey
