Crash when execute unbonding tx

Title:
Finding Security Vulnerabilities

Summary:
Crash when executing an unbonding transaction

Details:

1. Executing an unbonding transaction;
2. I tried to unbond the available tokens (which are displayed before the transaction is executed), also I think it is worth considering that at the time I tried to do this my validator was in jail;
3. I sent a transaction of the form namadac unbond --validator "" --source "" --amount "" --memo "" --node ""(I'm not sure if I specified the "--source" flag, so that could also be the cause of the error).

Our validator address: tnam1q9raezgmgfz6rr68uuv47y8rn0gnufl9zqvdaqes

Error message:
