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.

| LINKER_ERROR | This 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 |
