T3003: Invalid contract field ​

Cause ​

A contract field has the wrong shape or an invalid value (a string where an array is needed, a bad name).

Example ​

xml
<contract>
{ "name": "Card", "role": "group", "parts": ["root"], "variants": { "tone": "primary" } }
</contract>
<template><div class="root"></div></template>

What you see ​

text
ERROR  T3003  app/components/Card.tess:2:77
  Variant "tone" must be an array of allowed values.
  Run `tessera explain T3003` for details.

Fix ​

Fix the field the message names.
