Oh, ok - I received success message and I got a link to check transaction but there was an only message: SORRY, WE COULD NOT FIND ANY RESULTS MATCHING.
You need to add --allega-era to your command, as testnet is in Allegra now.
Sounds like you also need to update your cardano-node and cardano-cli to be 1.24.2 or higher. The mentioned command syntax works only post 1.24.2, and nodes prior will not be able to sync further.
Thank you very much! I have one more question: if testnet is in Allegra which of config files should I use? From Allegra or from testnet? Cardano Configurations
The page you referred to are name of the networks (agree-ably the nomen clature of some of them conflicts with the actual era), but since you’re using testnet network, you can stick to using config corresponding to testnet row.
