Error Summary

Mining

Worker

Error name	Meaning	Solution
WorkerNotRegistered	The worker is not registered in the registry when adding to the pool	Check the synchronization process and mining status of the worker
BenchmarkMissing	The worker doesn’t have a valid benchmark when adding to the pool	Make sure the worker is mining and wait for the benchmark uploaded
WorkerDoesNotExist	The worker is already added to the pool	-
WorkerInAnotherPool	The worker is already added to another pool	Remove it from the pool to which the worker is added before if it’s not the pool you want to add the worker to
UnauthorizedOperator	The access to a worker is granted by its operator parameter set by register_worker	Check the config on the mining scripts
InsufficientFreeStake	Cannot start mining because there’s no enough free stake	The stake amount you set to the work is more than the free stake amount in the pool. Set a number that is less than the free stake or delegates more PHA in the pool
WorkersExceedLimit	Failed to add a worker because the number of the workers exceeds the upper limit.	Create another pool or remove the useless worker in this pool (Make sure the worker is stopped and reclaimed before you remove it)
CannotRestartWithLessStake	Restarted with a less stake is not allowed in the tokenomic.	-
MinerNotReady	Miner is not in Ready state to proceed.	Wait for a 7 days period of Cool-down and reclaim it when the period is finished
MinerNotMining	Miner is not in Mining state to stop mining.	-
CoolDownNotReady	Cannot reclaim the worker because it’s still in cooldown period.	Wait for the 7 days period of Cool-down and reclaim it when the period is finished
TooMuchStake	Cannot start mining because there’s too much stake (exceeds Vmax).	The stake amount you set for the worker is more than the maximum stake amount of the worker. Set a lower number and try again. How to calculate the maximum stake: Phala Tokenomics
BenchmarkTooLow	Indicating the initial benchmark score is too low to start mining.	Make sure your worker has a high-quality computing power. Restart your mining scripts and check the mining score on the mining status. If the mining score is still under 100, the worker will not be allowed to participate the Phala Mining.
MinerNotFound	Miner not found.	-
MinerNotBound	Not permitted because the miner is not bound with a worker.	-
WorkerNotBound	Not permitted because the worker is not bound with a miner account.	-
InternalErrorBadTokenomicParameters	Internal error. The tokenomic parameter is not set.	Please contact the Phala Team the bug you meet, thank you

Pool

Error name	Meaning	Solution
InadequateCapacity	The stake capacity is set too low to cover the existing stake	Set a higher cap that is not less than the amount of existing delegation
NoRewardToClaim	There’s no pending reward to claim	Keep patient and learn about the Principles of payment events
AlreadyInContributeWhitelist	Can not add the staker to whitelist because the staker is already in whitelist.	-
ExceedWhitelistMaxLen	Too many stakers in contribution whitelist that exceed the limit	remove the useless whitelist in this pool

Delegate

Error name	Meaning	Solution
StakeExceedsCapacity	The stake added to a pool exceeds its capacity	You can’t add the delegation amount more than the delegatable amount of the pool
InsufficientContribution	The contributed stake is smaller than the minimum threshold	Set a delegation amount that is more than 0.01 PHA
InsufficientBalance	Trying to contribute more than the available balance	You don’t have enough transferrable balance. Check your transferrable balance
InvalidWithdrawalAmount	The withdrawal amount is too small (considered as dust)	The withdrawal amount should be more than 0.01 PHA
NoRewardToClaim	There’s no pending reward to claim	Keep patient and learn about the Principles of payment events
NotInContributeWhitelist	Invalid staker to contribute because origin isn’t in Pool’s contribution whitelist.	Ask the pool owner to add you to the whitelist
