Transaction version (0) is not supported by the requesting client, set maxSupportedTransactionVersion

[kskalski]

This is probably due to old anchor dependency used by @pythnetwork/pyth-solana-receiver

node_modules/@solana/web3.js/src/connection.ts:5069
      throw new SolanaJSONRPCError(res.error, 'failed to get transaction');
            ^

I've seen this error before, and never understood how to fix it.

To validate your hypothesis that this is due to an outdated anchor dependency, could you try dispatching the transaction using some anchor-less logic like https://github.com/pyth-network/pyth-crosschain/blob/main/target_chains/solana/sdk/js/solana_utils/src/transaction.ts#L416 ?

Also would be useful if you could provide more context.

I faced this same error yesterday, and after upgrading @solana/web3.js to ^1.98.0, it seemed to have fix this issue
