Bug report

• Indexing stops for the specific subgraphs

We are using graph node for our L2 network using Optimism. But sometimes, the below error occurs and indexing is stopped for the specific subgraphs. I have never seen the error. How can I do to resolve the error?

You can see the indexing status using below query in here (https://graph-node.titan-sepolia.tokamak.network/graphql/playground)

{
  indexingStatuses(subgraphs: ["QmNa9YZ58oSRqjtFRNxufXpNTvJ5dRZAMn4nisRAPtL17y"]) {
    subgraph
    synced
    health
    paused
    node
    entityCount
    fatalError {
      handler
      message
      deterministic
      block {
        hash
        number
      }
    }
    nonFatalErrors {
      handler
      message
      deterministic
      block {
        hash
        number
      }
    }
    chains {
      chainHeadBlock {
        number
      }
      earliestBlock {
        number
      }
      latestBlock {
        number
      }
    }
  }
}

Thank you very much.
