The Error enum of this pallet.

Variants

InvalidSchedule

Invalid schedule supplied, e.g. with zero weight of a basic operation.

InvalidCallFlags

Invalid combination of flags supplied to seal_call or seal_delegate_call.

OutOfGas

The executed contract exhausted its gas limit.

OutputBufferTooSmall

The output buffer supplied to a contract API call was too small.

TransferFailed

Performing the requested transfer failed. Probably because there isn’t enough free balance in the sender’s account.

MaxCallDepthReached

Performing a call was denied because the calling depth reached the limit of what is specified in the schedule.

ContractNotFound

No contract was found at the specified address.

CodeTooLarge

The code supplied to instantiate_with_code exceeds the limit specified in the current schedule.

CodeNotFound

No code could be found at the supplied code hash.

CodeInfoNotFound

No code info could be found at the supplied code hash.

OutOfBounds

A buffer outside of sandbox memory was passed to a contract API function.

DecodingFailed

Input passed to a contract API function failed to decode as expected type.

ContractTrapped

Contract trapped during execution.

ValueTooLarge

The size defined in T::MaxValueSize was exceeded.

TerminatedWhileReentrant

Termination of a contract is not allowed while the contract is already on the call stack. Can be triggered by seal_terminate.

InputForwarded

seal_call forwarded this contracts input. It therefore is no longer available.

RandomSubjectTooLong

The subject passed to seal_random exceeds the limit.

TooManyTopics

The amount of topics passed to seal_deposit_events exceeds the limit.

NoChainExtension

The chain does not provide a chain extension. Calling the chain extension results in this error. Note that this usually shouldn’t happen as deploying such contracts is rejected.

XCMDecodeFailed

Failed to decode the XCM program.

DuplicateContract

A contract with the same AccountId already exists.

TerminatedInConstructor

A contract self destructed in its constructor.

This can be triggered by a call to seal_terminate.

ReentranceDenied

A call tried to invoke a contract that is flagged as non-reentrant. The only other cause is that a call from a contract into the runtime tried to call back into pallet-contracts. This would make the whole pallet reentrant with regard to contract code execution which is not supported.

StateChangeDenied

A contract attempted to invoke a state modifying API while being in read-only mode.

StorageDepositNotEnoughFunds

Origin doesn’t have enough balance to pay the required storage deposits.

StorageDepositLimitExhausted

More storage was created than allowed by the storage deposit limit.

CodeInUse

Code removal was denied because the code is still in use by at least one contract.

ContractReverted

The contract ran to completion but decided to revert its storage changes. Please note that this error is only returned from extrinsics. When called directly or via RPC an Ok will be returned. In this case the caller needs to inspect the flags to determine whether a reversion has taken place.

CodeRejected

The contract’s code was found to be invalid during validation.

The most likely cause of this is that an API was used which is not supported by the node. This happens if an older node is used with a new version of ink!. Try updating your node to the newest available version.

A more detailed error can be found on the node console if debug messages are enabled by supplying -lruntime::contracts=debug.

Indeterministic

An indeterministic code was used in a context where this is not permitted.

MigrationInProgress

A pending migration needs to complete before the extrinsic can be called.

NoMigrationPerformed

Migrate dispatch call was attempted but no migration was performed.

MaxDelegateDependenciesReached

The contract has reached its maximum number of delegate dependencies.

DelegateDependencyNotFound

The dependency was not found in the contract’s delegate dependencies.

DelegateDependencyAlreadyExists

The contract already depends on the given delegate dependency.

CannotAddSelfAsDelegateDependency

Can not add a delegate dependency to the code hash of the contract itself.

OutOfTransientStorage

Can not add more data to transient storage.
