# 520063: Trait is not registered in the memory store

Log Type: TWILIO

Log Level: ERROR

## Description

One or more traits named in the trait extraction strategy's definitions are not registered in the memory store's trait registry.

### Possible causes

* The trait group or trait name is misspelled.
* The trait was never added to the memory store.
* The trait group was deleted after the trait extraction strategy was created.

### Possible solutions

* List the memory store's trait groups to verify the trait group and trait names, and then retry.
* Add the missing trait to the memory store before referencing it in a trait extraction strategy.
