# Why do I get an error for challenge 2012?

The following error message can be ignored for challenge 2012:

`Error submitting assertion for Sentry Key [X] to challenge 2012 - execution reverted`

This error occurs only for challenge 2012 because when the staking tiers were updated on 3/2/24, operators on the outdated version (1.1.3 and older) were still attempting to submit challenges which were invalid. 

A permanent fix for the error is underway. All rewards are working normally.
