Flow Mainnet will be sporking on 2023-04-26 at 08:00 AM PT/ 3:00 pm UTC going from Mainnet-22 to Mainnet-23.

The Flow access nodes will be turned off during that time. Once the spork is complete, at around 8:25 AM PT, a message will be posted on the message forum and Discord requesting you to start your nodes.

Please ensure you have subscribed for updates on http://forum.flow.com/c/mainnet-sporks or have joined the Discord #flow-validators channel.

Your keys will be carried from the current spork, so there is no need to resubmit the keys.

We will request you start your node at around 8:25 AM.

ACTIONS needed from your side on 2023-04-26:

Perform Step 1 and then Step 2 when you see the announcement “Mainnet Spork Complete” on the forum or Discord.

As always, feel free to reach out on discord for support.

Thank you,
Flow Team

I am calling to retrieve for example this event “A.921ea449dffec68a.Flovatar.Created”

and I used different block ranges and using gRPC call GetEventsForHeightRange

startBlock=38848642&endBlock=38848742
in this case it is access-node, access-001.mainnet20.nodes.onflow.org:9000
Here the error code is 13
