What it means
Assembling, compiling, signing and size-checking transaction messages.
What to do
- Set a fee payer and a lifetime (blockhash or durable nonce) before compiling.
- Keep the serialised transaction at or under 1,232 bytes; use address lookup tables for large transactions.
- A durable-nonce transaction must have
AdvanceNonceAccount as its first instruction.
Decode it locally instead
npx @solana/errors decode -- 5663034 '<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__TRANSACTION__TOO_MANY_INSTRUCTIONS) lets you branch on it.
