What went wrong?

After upgrading to oracle release binary, the following error is reported every time after a node is restarted.

sage":"Error starting Oracle Keeper price feeder"}

It doesn't affect the operation of the price feeder but it doesn't emit prometheus metrics related to the price feeder.

It's possible that the duplicate registration happens here:

How can we reproduce this bug?

1.Start a devnet using v4.1.5 binaries and submit software upgrade proposal to upgrade to v4-feature handler
2. Upgrade devnet to v4.2.0-develop.2
3. Restart node after software upgrade.
