ReferenceErrors

`type.constraint_base`

Constraint does not fit the type's base.

Area 2, Values and types; not declinable; the next step is usually the agent's.

example

type Nickname = Text {    min: 1}

jadpo checkcheck failed: 1 error, 1 file

error min doesn't apply to a Text type

--> main.jadpo:2:5

  |2 |     min: 1  |     ^^^ doesn't fit the base

reason: min constrains Int, Decimal, Duration, Money, Percentage and quantity types.
next: Remove min, or use a constraint that fits (agent)
rule: type.constraint_base
