Error Codes

Error Codes in Aptos

This page catalogs common errors encountered in the Aptos blockchain and explains how to resolve them wherever possible. As with all software, the code itself is the source of truth for error handling and will always contain entries not found here. Instead, this matrix aims to help you address those errors most typically found, misunderstood, or both.

For the sources of these errors, see:

Help us update this list by sending pull requests containing the errors you encounter. If you don’t know how to resolve the error, as described int the Action column, simply leave it blank.

Move Virtual Machine (VM)

ErrorMeaningPossible Resolution
LOOKUP_FAILEDA function that is being called isn’t present on the network being usedCheck that your dependencies on-chain have the same version
UNKNOWN_VALIDATION_STATUSWe don’t want the default value to be valid.N/A

DUPLICATE_MODULE_NAMEThe sender is trying to publish two modules with the same name in one transaction.Confirm every module has a unique name
BACKWARD_INCOMPATIBLE_MODULE_UPDATEThe sender is trying to publish a module that breaks the compatibility checks.Confirm your new modules being published don’t break backwards compatibility
CYCLIC_MODULE_DEPENDENCYThe updated module introduces a cyclic dependency (i.e., A uses B and B also uses A).Check for loops in your module dependencies in the modules being published

LOOP_MAX_DEPTH_REACHEDLoops are too deeply nested.Check for many nested loops
TYPE_RESOLUTION_FAILUREFailed to resolve type due to linking being broken after verification.N/A
RESOURCE_DOES_NOT_EXISTWe tried to access a resource that does not exist under the account.Check the contract and possibly change it to handle resources that don’t exist
RESOURCE_ALREADY_EXISTSWe tried to create a resource under an account where that resource already exists.Check the contract and possibly change it to handle resources that already exist
UNKNOWN_STATUSA reserved status to represent an unknown vm status. This is std::u64::MAX, but we can’t pattern match on that, so put the hardcoded value in.N/A
LINKER_ERRORThis may be due to the function has not been published on chain or by trying to call an invalid function as the result of either an incorrect account address, module name, or function name. This might not happen locally if the sources are available locally but have yet to be published on-chain.There are many reasons, but you should check your account addresses, module names, and function names to determine that they’re correct and published
