CODECS__INVALID_DISCRIMINATED_UNION_VARIANT
Appears as Solana error #8078009; Decode this error by running `npx @solana/errors decode -- 8078009 '…'`
Message
Invalid discriminated union variant. Expected one of [$variants], got $value.
Placeholders (variants, value) are filled from the error’s context. Paste the base64 argument below to see the real values.
What it means
Encoding and decoding bytes: wrong sizes, out-of-range numbers, enum discriminators, sentinels, invalid strings.
What to do
- Match the codec exactly to the on-chain layout: integer width, endianness, prefix sizes and option encoding.
EXPECTED_DECODER_TO_CONSUME_ENTIRE_BYTE_ARRAY usually means the decoder is for a different account version.
Decode it locally instead
npx @solana/errors decode -- 8078009 '<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__CODECS__INVALID_DISCRIMINATED_UNION_VARIANT) lets you branch on it.
