OFFCHAIN_MESSAGE__VERSION_NUMBER_NOT_SUPPORTED
Appears as Solana error #5607006; Decode this error by running `npx @solana/errors decode -- 5607006 '…'`
Message
This version of Kit does not support decoding offchain messages with version $unsupportedVersion. The current max supported version is 0.
Placeholders (unsupportedVersion) are filled from the error’s context. Paste the base64 argument below to see the real values.
What it means
Encoding and validating off-chain signed messages (application domain, format, length limits).
What to do
- Follow the off-chain message spec: version, application domain (32 bytes), format and length limits per format.
Decode it locally instead
npx @solana/errors decode -- 5607006 '<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__OFFCHAIN_MESSAGE__VERSION_NUMBER_NOT_SUPPORTED) lets you branch on it.
