Zksync-era-test is not supported

the graph.com said that the zksync era is supported, but when deploying, raised error:
Specified network is not supported.


This issue seems to be related to zkSync Alpha (zkSync2-testnet) not available on Studio but listed as available · Issue #1367 · graphprotocol/graph-tooling · GitHub
I’ve pinged the team internally.

In the meantime, you can try deploying it to the Hosted Service using the slug zkSync2-testnet.
