SUMMARY

When attempting to write a new entry using the kwallet-query CLI, the command silently ignores the write operation and returns with a 0 exit code, indicating success despite the operation not being performed as expected. The issue lies within the QueryDriver::writeValue() function in querydriver.cpp, where the kind variable is assigned KWallet::Wallet::Unknown, causing the function to prematurely call quit(). 

STEPS TO REPRODUCE
Attempt to write a new entry in KWallet using the kwallet-query CLI.
echo "test" | kwallet-query kdewallet -w mypassword

OBSERVED RESULT
The command returns with a 0 exit code without actually writing the entry.  Check that entry does not exist via KWalletManager or via cli:
kwallet-query kdewallet -l

EXPECTED RESULT
kwallet-query command should correctly write the new entry with the provided data, and the CLI should reflect success or failure based on the actual outcome.

ADDITIONAL INFORMATION
Workaround:
