Long card description --> Indexing fails

[besca-red]

Describe the bug After creating a card with a long description an error occurs in the log. After creating this card, no changes (title, description) to this card can be made. Every change attempt fails and produces an error in the log.

To Reproduce Steps to reproduce the behavior:

1. Go to Deck
2. Create a card
3. Write a long description (in my case: ~3.900 letters)
4. See error

Expected behavior Should work.
