Understanding the Amazing Fields Storage Exceeded Warning
Trello enforces hard limits on how much data a Power-Up can store on a board or a card. Amazing Fields compresses data to help you get as much as possible within these limits, but when a limit is reached, it displays a warning. This article explains what causes each type of storage warning and how to resolve it.
Note: This is a board-level data limit, not a card limit. If you're seeing a card storage exceeded warning instead, see: Understanding the Amazing Fields Card Storage Exceeded Warning.
Board storage exceeded
This warning appears when the total configuration data for your fields exceeds the storage limit for the board itself. This typically happens when:
- A very large number of fields are configured on the board
- A dropdown field has a very large number of options (50+ items with long descriptions)
Workaround: Use a Card Reference Field for large dropdown lists
The most common cause of board storage issues is a dropdown field with a very large list of options. The recommended workaround is to replace it with a Card Reference field. To set up a card reference field, see: How to add a card reference field.
Note: Card reference fields are available to supporters on the Advanced and Ultimate tiers. If you're on the free plan, upgrade to unlock this feature.
Tip: If you cannot identify the cause of the board storage issue, review your fields for any with unusually complex configurations, such as many conditional styling rules, long dropdown option lists, or extensive field descriptions. One or two fields are usually responsible.
