## What it means

The API answers with HTTP 400 Bad Request and an `application/problem+json` document when the condition is Card placement is invalid. The document's `type` member is `https://screenrig.ai/problems/card-invalid`, the address of this page, and its `code` member is `card_invalid`.

## What to do

errors[0].field names the placement member the card catalog refused and errors[0].card names the card. Use a built-in card id, its current major, and only its static params; dynamic properties belong in the card data document the placement's data key names.
