I can't use my old Tx creator (cardano-cli) from Alonzo era.
Command failed: transaction build Error:
The era of the node and the tx do not match.
The node is running in the Babbage era, but the transaction is for the Alonzo era.
\n"}
How can I create babbage era tx. Whats the difference from Alonzo Era?
You can probably just add --babbage-era to your cardano-cli transaction build (or build-raw) command. You'll see this option when you enter cardano-cli transaction build -h.
As per this issue and this comment the alonzo-era is still set as the default for now.
Regarding the differences, the babbage era brings lots of new features and possibilities, that you can find a good technical overview of here, including: reference inputs, reference scripts, inline datums and much more.
