Description

When using the latest release v0.22.0 I'm getting this RPC timeout bellow. I've tried to switch between two different RPC providers but I get the same issue. I then downgraded to the previous version sha-6717d55 and the queue started to be processed and no more RPC timeouts

Research direction

Start with packages/indexer-common/dist/indexer-management/monitor.js at the failed network-pause check and trace the eth_blockNumber request shown in the log. Compare behavior between v0.22.0 and sha-6717d55, then reproduce against the reported RPC endpoint. Done means the queue is processed without the reported RPC timeout.
