ERROR_STATE_SETTING_NAME_SIZE_LIMIT_EXCEEDED

The setting name is too long

ERROR_STATE_SETTING_NAME_SIZE_LIMIT_EXCEEDED indicates that the key name, not its value, violates the repository limit. Dynamic names built from paths, URLs, user text, or compound identifiers are common sources.

Resolution

  • Use stable short keys defined by the application schema.
  • Store long external identifiers as values rather than key names.
  • Hash only when collision handling and diagnostics are designed explicitly.
  • Validate length after final encoding and normalization.

Migration concern

If an older implementation generated overlong names elsewhere, define a deterministic mapping so existing data is not orphaned.

Stable schema design

Setting names should be identifiers chosen by the application, not containers for arbitrary external data. Keep them short, documented, and independent of localization.

Collision-safe alternatives

If an external identifier must select a value, store a compact generated ID as the key and maintain the original identifier inside the value. When hashing is used, include collision detection rather than assuming uniqueness.
