file not found "pool.keys"

[S1700]

When running the monero wallet command and checking the logs is see this:

Here is the command I used to run the monero-wallet-rpc, pm2 start /usr/local/src/monero/build/release/bin/monero-wallet-rpc -- --rpc-bind-port 18081 --password-file ~/wallet_pass --wallet-file pool --disable-rpc-login --trusted-daemon

Note: Yes the pool.keys file does exist and yes I have tried running it under the same directory as the file
