Our indexer has gotten stuck with this error:

{“error”:“AddBlock() err: TxWithRetry() err: attemptTx() err: AddBlock() eval err: EvalForIndexer() err: overflowed subtracting rewards for block 20537415”,“level”:“error”,“msg”:“adding block 20537415 to database failed”,“time”:“2022-04-23T20:09:44+02:00”}

We may have inadvertently caused this by running a background reindex (REINDEX CONCURRENTLY) while the indexer was running.

Any tips on how to get it unstuck?
