Describe what the problem is?

I got an unexpected error message when starting kupo:

❯ kupo \
        --node-socket ~/programs/cardano-node-1.35.4-linux/mainnet/db/node.socket \
        --node-config ~/programs/cardano-node-1.35.4-linux/configuration/cardano/mainnet-config.json \
        --since origin \
        --defer-db-indexes \
        --match "*/stake_vkh14hkp0sncfkt76spuqydtww4r900hfmsseezztzlh9sjkkjx6d7q" \
        --workdir ./db
kupo: SQLite3 returned ErrorCan'tOpen while attempting to perform open "file:./db/kupo.sqlite3?mode=rwc": unable to open database file

What should be the expected behavior?

I figured that I simply needed to create the db workdir I'm passing as argument. I would have expected kupo to check for the existence of the workdir and either tell me it does not exist or create it itself. I wasn't expected to reach a crash with the a default sqlite error message.

Good point.

Alternatively: we could try to create the folder path recursively if it's not there.
