Failed to parse account ID: {e}

Error message

Failed to parse account ID: {e}

What it means

The credential's account_id() accessor parses the stored bech32 address string back into an AccountId. If the address string cannot be parsed as a valid bech32 account ID, this error is thrown. Since the address is produced internally at construction, failure implies corrupt or malformed stored state.

Solutions

1. Ensure credentials are constructed via from_private_key so the address is valid by construction
2. Validate the address format before persisting or deserializing credential state
3. Recreate credentials from the private key instead of reconstructing from partial data

Example fix

// before
let creds = DyDxCredentials { address: stored_address.clone(), .. };
let id = creds.account_id()?; // may fail
// after
let creds = DyDxCredentials::from_private_key(private_key, authenticator_ids)?; // address guaranteed valid
let id = creds.account_id()?;

fn looks_like_dydx_address(a: &str) -> bool { a.starts_with("dydx") && a.len() >= 20 }

let id = creds.account_id().or_else(|_| DyDxCredentials::from_private_key(&key, ids.clone()).and_then(|c| c.account_id()))?;

When it happens

Trigger: Calling DyDxCredentials::account_id() when the internal address string is empty, truncated, or otherwise not a valid dYdX bech32 address (e.g. a Credentials instance built through a path that set address manually).

Common situations: Deserializing credentials from storage/config where the address field was corrupted; test fixtures with fake address strings.
