This is the error I get: Invalid document reference. Document references must have an even number of segments, but membres/UVLPL9kxP1hGuiwCStS4oDLJvxo1/projets has 3.

    The error message is quite clear: you are trying to write to a document at path /membres/$uid/projects, but that is the path of a collection.

    If you want to add a document to that subcollection, use addDoc instead of setDoc.

    addDoc works like that:

    addDoc(CollectionReference //i.e collection(db, "path"), element)
