API Returns Cannot submit an array as a custom attribute value Hello, We created a custom attribute with the list type called `Channel Networks`. When we try to update it via the API we get back the following error:```{ type: 'error.list', request_id: 'REDACTED', errors: [ { code: 'nested_custom_attributes', message: 'Cannot submit an array as a custom attribute value' } ]}```Other custom attributes work fine, just list/array type ones fail.```const respIntercom = await fetch(`https://api.intercom.io/contacts/${contact_id}`,{method: 'PUT',headers: {'Content-Type': 'application/json','Intercom-Version': '2.12',Authorization: `Bearer ${process.env.INTERCOM_ACCESS_TOKEN}`},body: JSON.stringify({"name": userData.user.name + " TEST","phone": userData.user.phone,"last_seen_at": userData.user.last_online,"signed_up_at": userData.user.created_at,"custom_attributes": {"ACME": userData.user.acme,"Channel Networks": ["Channel 1", "Channel 2"],}})});```
