Appears as Solana error #8500007; Decode this error by running `npx @solana/errors decode -- 8500007 '…'`
Message
Expected resolved instruction input '$inputName' to be a `TransactionSigner` because the instruction requires this account to sign the transaction. If its signature is provided by other means, use `createNoopSigner()` from `@solana/signers` to satisfy this requirement.
Placeholders (inputName) are filled from the error’s context. Paste the base64 argument below to see the real values.
What it means

What to do
- Make sure the client matches the deployed program version and that you are calling the right program address.
Decode it locally instead
npx @solana/errors decode -- 8500007 '<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__PROGRAM_CLIENTS__RESOLVED_INSTRUCTION_INPUT_MUST_BE_SIGNER) lets you branch on it.
