Trying to add a column to users returns "No data in schema update request"

REST API

I’m new to DF and I’m having trouble adding a field to the users table. When I run the following through the API using db/_schema - “updateAppdendbTables() - Update (patch) one or more tables.” I get “No data in schema update request”. Can someone tell me what I’m doing wrong? Thanks!

{
“resource”: [
{
“name”: “users”,
“field”: [
{
“name”: “ein”,
“type”: “string”
},
]
}
]
}

The users table is not editable (except directly in the database) and is not extensible at all in this way.
If you wish to use additional fields associated with users, take a look at the user/custom api call.
