INSTRUCTION__EXPECTED_TO_HAVE_DATA
Appears as Solana error #4128001; Decode this error by running `npx @solana/errors decode -- 4128001 '…'`
The instruction does not have any data.
An instruction object is missing data, accounts or the expected program address.
npx @solana/errors decode -- 4128001 '<base64 context>'In development, import from @solana/kit as usual and the full message is thrown. In production the message is stripped to keep bundles small; the error object still carries error.context with the same values this page decodes, and isSolanaError(err, SOLANA_ERROR__INSTRUCTION__EXPECTED_TO_HAVE_DATA) lets you branch on it.
