Errors
All errors thrown from the SDK are instances of the FuelError
class which will have an accompanying ErrorCode
.
Error Codes
Here is a list of the expected error codes the SDK can throw. These error codes are used to help understand the error that has been thrown with potential resolutions.
ABI_MAIN_METHOD_MISSING
When your ABI does not have a main
method.
This can be resolved by adding a main
method to your ABI. This is prevalent in scripts and predicates that must contain a main
method.
ABI_TYPES_AND_VALUES_MISMATCH
When the arguments supplied to the function do not match the minimum required input length.
Check that the arguments supplied to the function match the required type.
ACCOUNT_REQUIRED
When an Account
is required for an operation.
It could be caused during the deployments of contracts when an account is required to sign the transaction. This can be resolved by following the deployment guide here.
CONFIG_FILE_NOT_FOUND
When a configuration file is not found. This could either be a fuels.config.[ts,js,mjs,cjs]
file or a TOML file.
Ensure that the configuration file is present in the root directory of your project.
CONFIG_FILE_ALREADY_EXISTS
When a configuration file already exists in the root directory of your project.
You can not run fuels init
more than once for a given project. Either remove the existing configuration file or update it.
CONVERTING_FAILED
When converting a big number into an incompatible format.
Ensure that the value you've supplied to the big number is compatible with the value you are converting to.
CONTRACT_SIZE_EXCEEDS_LIMIT
When the contract size exceeds the maximum contract size limit.
Ensure that the contract size is less than the maximum contract size limit, of 100 KB. This can be validated by checking the bytecode length of the contract.
DUPLICATED_POLICY
When there are more than policies with the same type, for a transaction.
Ensure that there are no duplicate (by type) policies for a transaction.
ERROR_BUILDING_BLOCK_EXPLORER_URL
When more than one of the following options is passed: path
, address

GAS_PRICE_TOO_LOW
When the gas price is lower than the minimum gas price.
Increase the gas price to be greater than the minimum gas price.

Ensure that the entropy is between 16 and 32 bytes and a multiple of 4.
INVALID_EVM_ADDRESS

The error message will determine which parameter is missing. It could be that the provided program type is not one of the following contract
, script
, or predicate
.
INVALID_MNEMONIC
When the supplied mnemonic is invalid.
Check the message for more details. It could be that the mnemonic phrase word length is not one of the following: 12, 15, 18, 21, or 24 lengths.
INVALID_PASSWORD
When the provided password is incorrect.
Ensure that the password is correct.
INVALID_POLICY_TYPE
When the supplied policy type is invalid for the given Script.
Check the policy type is defined in PolicyType
.
INVALID_PROVIDER
When unable to connect to the Provider
or Network
supplied to a method on the Fuel
class.
Check that the Provider
or Network
is supplied correctly.
INVALID_PUBLIC_KEY
When the provided public key is invalid.
Ensure that the public key is valid.
INVALID_RECEIPT_TYPE
When the receipt type is invalid.
Check the type is within ReceiptType
.
INVALID_REQUEST
When the request to the Fuel node fails, error messages are propagated from the Fuel node.
Check the error message from the Fuel node.
INVALID_SEED
When the seed length is not between 16 and 64 bytes.
Ensure that the seed length is between 16 and 64 bytes.
INVALID_TRANSACTION_INPUT
When the input type is invalid.
Check the type is within InputType
.
INVALID_TRANSACTION_OUTPUT
When the output type is invalid.
Check the type is within OutputType
.
INVALID_TRANSACTION_STATUS
When the transaction status received from the node is unexpected.
Check the status received is within TransactionStatus
.
UNSUPPORTED_TRANSACTION_TYPE
When the transaction type from the Fuel Node is not supported.
The type is within TransactionType
.
INVALID_TTL
When the TTL is less than or equal to zero.
Ensure that the TTL is a number and that the TTL is greater than zero.
INVALID_WORD_LIST
When the word list length is not equal to 2048.
The word list provided to the mnemonic length should be equal to 2048.
INVALID_URL
When the URL provided is invalid.
Ensure that the URL is valid.
JSON_ABI_ERROR
When an ABI type does not conform to the correct format.
It is usually caused by an incorrect type/s within your program, check our type docs here for information on the types we support and their expected format.
LOG_TYPE_NOT_FOUND
When the log type ID supplied can not be found in the ABI.
Check that the log type ID is correct and exists in the ABI.
MISSING_CONNECTOR
A connector is missing when it's required for a given operation.
Ensure that a connector has been supplied to the Account
or Wallet
.
MISSING_PROVIDER
A provider is missing when it's required for a given operation.
It could be caused by the provider not being set for either an Account
or a Wallet
- use the connect
method to attach a provider.
MISSING_REQUIRED_PARAMETER
When a required parameter has not been supplied to a given method.
The error message will determine which parameter is missing. This could be caused during type generation when neither inputs
nor filepaths
are supplied (at least one is required).
NODE_INFO_CACHE_EMPTY
When the Fuel Node info cache is empty; This is usually caused by not being connected to the Fuel Node.
Ensure that the provider has connected to a Fuel Node successfully.
NOT_ENOUGH_FUNDS
When the account sending the transaction does not have enough funds to cover the fee.
Ensure that the account creating the transaction has been funded appropriately.
TIMEOUT_EXCEEDED
When the timeout has been exceeded for a given operation.
Check that you're connected to the network and that the network is stable.
TYPE_NOT_FOUND
When the type with the given type ID is not found in the ABI.
Check that the type ID is correct and exists in the ABI.
TYPE_NOT_SUPPORTED
When an unexpected type has been detected - the error message will determine which type is incorrect.
Check the type against your ABI and ensure that it is correct. You can find a list of all our types here.
UNSUPPORTED_FUEL_CLIENT_VERSION
When the version of the Fuel Node you are targeting is not supported by the client you are accessing it from.
Check the version of the Fuel Node and use a compatible version of the SDK to target it.
WALLET_MANAGER_ERROR
A wallet manager will throw for a multitude of reasons. The error message will determine which element of the configuration is incorrect.
It could be that the passphrase is incorrect and/or the wallet does not exist in the manager.
WORKSPACE_NOT_DETECTED
When the workspace is not detected in the directory indicated in the message.
Ensure that the workspace is present in the directory specified.
UNKNOWN
In cases where the error hasn't been mapped yet, this code will be used.
If you believe you found a bug, please report the issue to the team.
MAX_INPUTS_EXCEEDED
When the number of transaction inputs exceeds the maximum limit allowed by the blockchain.
MAX_OUTPUTS_EXCEEDED
When the number of transaction outputs exceeds the maximum limit allowed by the blockchain.
MAX_COINS_REACHED
When performing a funding operation, or calling getResourcesToSpend
, this error can be thrown if the number of coins fetched per asset exceeds the maximum limit allowed by the blockchain.
This can be avoided by paginating the results of the getCoins
method to fund your transaction, or by reducing the number of UTXOs for your account. This can be done by performing a transfer that amalgamates your UTXOs, as demonstrated in this cookbook.
