What the error means
Transaction loads an address table account that doesn't exist
The versioned transaction points to an address lookup table that is not on this network, was closed, or the app used a table from a different cluster.
| Where it comes from | Solana runtime (transaction error) |
| Code | AddressLookupTableNotFound |
How to fix it
- Check the network: a lookup table on mainnet does not exist on devnet.
- If the app manages its own lookup table, recreate or extend it and rebuild the transaction.
- Fall back to a legacy transaction if the instruction fits in 1,232 bytes without a table.
If that is not it
- If the table exists, the error may instead say it has an invalid owner or index; read the exact message.
