Update (PUT) probleme of ID

Hello everyone,
After a day of searching, I’m reaching out to the community for help ;-)

I need to perform an update (PUT) on a component with all the data. Nothing unusual.

But when I send my array, I get an ID error.

Error :
{ "data": null, "error": { "status": 400, "name": "ValidationError", "message": "Invalid key id", "details": { "key": "id", "source": "body" } } }

Here’s my code:
const updateData = async () => { await update('characters', data.value.documentId, { mastery: otherClassSkillsMastery.value }); }

And the request body:
{ "data": { "mastery": [ { "description": "eee", "id": 43, "name": "eeee" }, { "description": "e", "id": 44, "name": "eeee" }, { "description": "", "name": "aaa" } ] } }

Yet with Strapi 4, I’ve never had this kind of ID issue before.

No repository file or test is named. Start by reproducing the update('characters', data.value.documentId, ...) call with the shown mastery payload, then inspect the module's Strapi update entry point and how it handles nested objects containing id fields. Done means determining whether the request is transformed correctly or documenting the supported payload shape.
