Invalid iv in the message

gboudrea Unfortunately that's exactly how op item get works, here's the docs. https://developer.1password.com/docs/cli/reference/management-commands/item/#item-get

Requesting an item by name retrieves all the items you have access to from the 1Password servers, and then filters them by name client-side. This could result in hitting the rate limits quicker than expected. To limit the scope of the search, include the --vault flag.

As a workaround to troubleshoot before item level debugging is available, you could move a subset of items into another (or new) vault, maybe half of them, and ensure you filter to the original vault. Then you can repeat and narrow down to see when it's erroring and when it isn't.
