getSignaturesForAddress Returns Empty Array ([]) Despite Running Faithful RPC Server Successfully

[AshishG2]

When running the faithful-cli RPC server, most RPC methods function correctly. However, the getSignaturesForAddress method always returns an empty array ([]), even when querying addresses that have known transaction history. This issue persists despite using the latest available gsfa index.

Steps to Reproduce

1. Clone the repository and build the CLI binaries:

   git clone https://github.com/rpcpool/yellowstone-faithful.git
   cd yellowstone-faithful
   make jsonParsed-linux  # Or use the appropriate build command

2. Start the Faithful RPC Server:

   faithful-cli rpc --listen=:8888 epoch-701.yml

3. Query getSignaturesForAddress:

   curl -X POST http://localhost:8888 -H "Content-Type: application/json" -d '{
     "jsonrpc": "2.0",
     "id": 1,
     "method": "getSignaturesForAddress",
     "params": ["<wallet_address>"]
   }'

4. Observe the response:

   • Expected: A list of transaction signatures for the given address.
   • Actual: An empty array ([]), even when transactions exist.

GSFA Index Used

I am using the following gsfa index file:
📌 epoch-701-gsfa.index.tar.zstd

Expected vs. Actual Behavior

Query Method	Expected Response (Mainnet RPC)	Actual Response (Faithful RPC)
getSignaturesForAddress	List of transaction signatures	[] (empty array)

Additional Details

• Issue persists even with the latest gsfa index.
• Other RPC methods appear to be working correctly.
• No additional error messages appear in the Faithful server logs.

Would appreciate any guidance or troubleshooting steps on resolving this issue.

Possibly you need to find accounts that have signatures in that specific epoch?

If I check at the last block of epoch 701: https://explorer.solana.com/block/303263999
Take one of the txs: https://explorer.solana.com/tx/rhDpGxayZAfQa18SLZX1AsTVzzsptHEJaFuBB3NcfXqXFnAakTMeXAYzUgMamuskRojg3jQQi97LqyxMFGSv4uU

faithful-cli version | grep rev

I can see lots of results
