A starting table is defined with no name.

How to fix

Add the missing name property to your starting table definition.

Problem example:

{
  "startingTables": [
    {
      "table": {
        "schema": "dbo"
        // Missing "name" property
      },
      "filterClause": "Status = 'Active'"
    }
  ]
}

Fixed:

{
  "startingTables": [
    {
      "table": {
        "schema": "dbo",
        "name": "Users"  // Added missing name
      },
      "filterClause": "Status = 'Active'"
    }
  ]
}
