Mismatch between card ID and asset image ID

[MarcFrissekom]

Problem
Some cards appear with alphanumeric card numbers (for example 17A), but the corresponding asset image uses a completely different numeric identifier.

API card:
https://api.tcgdex.net/v2/en/cards/cel25-17a
Card number shown: 17A
Image is not returned by the API
However, the image exists manually at:
https://assets.tcgdex.net/en/swsh/cel25/47/high.jpg
This corresponds to Umbreon Gold Star (Celebrations).

So:
API card id: cel25-17a
Expected asset id: 17a
Actual asset id: 47
There does not appear to be a deterministic relationship between these values.
