Message
Not all accounts were decoded. Encoded accounts found at addresses: $addresses.

What it means
Helpers like fetchEncodedAccount and assertAccountExists.
What to do
- Confirm the address exists on the cluster your RPC points at.
- Decoding failures usually mean the account belongs to a different program or program version than the decoder expects.
