solana deposit lookup fails for the whole batch when one transaction is version 1
packages/solana/src/deposit.ts (line 127) fetches the deposit address's transactions with conn.getTransactions(signatures, { maxSupportedTransactionVersion: 0 }). If any of them is a version 1 transaction, the request fails with "Transaction version (1) is not supported by the requesting client", so one v1 transfer to a deposit address breaks the lookup for all of its deposits.
Version 1 transactions are a large share of mainnet now (about 40% of non-vote transactions in a block I sampled; 115 of 332 in another), so this depends only on which wallet or SDK built the transaction.
packages/solana/src/deposit.ts:127
getTransaction(<v1 signature>, { maxSupportedTransactionVersion: 0 }) -> error -32015 "Transaction version (1) is not supported by the requesting client"
getTransaction(<v1 signature>, { maxSupportedTransactionVersion: 1 }) -> the transaction (version 1, meta present)Fix: maxSupportedTransactionVersion: 1 (both calls in the file). @solana/web3.js 1.99.0 or later parses v1 fine with it (tested); 1.98.x rejects a version 1 answer even when asked, so it needs the bump too.
