# 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This error occurs only for challenge 2012 because when the staking tiers were updated on 3/2/24, operators on the outdated version (1.1.3 and older) were still attempting to submit challenges which were invalid.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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
