#1

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 https://forum.onflow.org/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.

Flow Port staking downtime during spork:

  • Flow Port will be inaccessible during the spork, and staking features will be disabled until 8:00 AM Pacific Time on 04/127/23.

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

For collection and consensus node operators: Hot-stuff start-up time is no longer needed.

Thank you,
Flow Team

gRPC calls to all past sporks since few days ago now fails with error

failed to retrieve events from execution nodes [execution-9[email protected]execution-001.mainnet18.nodes.onflow.org:3569=100]: 1 error occurred:\n’ +
'\t* rpc error: code = DeadlineExceeded desc = context deadline exceeded\n

Hi @asghaier can you share the gRPC call? Block ID etc?

Hi @vishal

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
details: ‘failed to retrieve events from execution nodes [execution-9686399a8a[email protected]-001.mainnet20.nodes.onflow.org:3569=100]: 1 error occurred:\n’ +
‘\t* rpc error: code = DeadlineExceeded desc = context deadline exceeded\n’ +

startBlock=41848642&endBlock=41848742
in this case it is access-node, access-001.mainnet21.nodes.onflow.org:9000
Here the error code is 4

‘\t* rpc error: code = DeadlineExceeded desc = context deadline exceeded\n’ +
‘\n’,

startBlock=48848642&endBlock=48848742
in this case it is access-node, access.mainnet.nodes.onflow.org:9000
in this case it is working and retrieving the events
