We are trying to update user_id for a bunch of intercom users but UpdateUser method is giving "400 - User already exists" error when trying to update user_id. We are calling this api for multiple users and for most it is giving 400 response. According to the API documentation, we should be able to update user_id when id is passed.
Params passed
{
id: <Intercom user id>,
user_id: <user Id to set>
}
We are using node intercom-client 2.11.2 with app token for API version 1.0
