Requests to gateway causes error

[Kristex95]

Recently, I've been using gateway and it worked fine. But suddenly every general endpoints started causing exceptions like this:

thread 'actix-rt|system:0|arbiter:0' panicked at ...cargo\git\checkouts\drift-rs-5caec46913ba7527\9d90de9\src\math\account_map_builder.rs:122:58: called Option::unwrap() on a None value

The endpoint used to produce error: /v2/collateral RPC node: https://mainnet.helius-rpc.com Public key: 6zuBS19Wtyof9EzWEinpsEJU2zPtXiHGCaxwwYT2URAR

It happens with other endpoint as well

Also, I've created second wallet for test purpose. It didn't work. So the issue is not in the account

thanks for reporting. it's likely due to rate limits being hit on startup as gateway tries to populate alot of data from chain. however the error should make this clearer and should find a way to make it more rate-limit friendly
