When we use on in gramex.yaml For example:

url:
  sqlite:
    pattern: /$YAMLURL/sqlite/
    handler: FormHandler
    kwargs:
      url: 'sqlite:///$YAMLPATH/mydatabase.db'
      table: [order_items, orders, customer]
      join:
        orders:
          type: inner
          on:
            order_tems.order_id: orders.id
        customers:
          join: left
          on:
            orders.customer_id: customers.id
      default:
        sales.amount>~: 0
        customer.age>~: 0

This fails because:

• YAML treats on: as True and creates True: {...}
• Gramex caches configurations as JSON in gramex.cache.cache_key()
• True is not a valid JSON key, and this raises an error. (Specifically, it's unable to sort str and bool together.)

We don't anticipate gramex.yaml having keys that are not strings. (We'll change on: to something else.)

Closing as won't fix.
