Bug report
Gemma from LunaNova has reported the following behaviour on the Arbitrum One network subgraph:
<@674203219349471262> did anyone have any clues? Our network subgraph is still failed and non-rewindable...
This morning I noticed that the network subgraph was somehow attempting to index on two indexer nodes simultaneously? We've stopped all but one indexer node now, so it can only be on one, but we're still seeing the same errors/issues.
A bit more info from the graph node logs...
We see this one multiple times, the block number increases...
INFO Subgraph error is still ahead of deployment head, nothing to unfail, error_block_hash: 0xeae04e55fda6358d1bbe2d1b1485e048631696888b00b9a011f10ace92562483, error_block_range: (Included(242816197), Unbounded), block_hash: 0xc78f776271180d1414d047a72c67c0cdc63d3de9eb87a9705c02de2f1334dbd7, block_number: 242810632, subgraph_id: QmSWxvd8SaQK6qZKJ7xtfxCCGoRzGnoi2WNzmJYYJW9BXY, shard: primary, component: Store
Then after a while (not always at the same block, it's random)
ERRO Subgraph writer failed, error: internal constraint violated: expected to remove at most one offchain data source but would remove 2, causality region: 35120, sgd: 969, subgraph_id: QmSWxvd8SaQK6qZKJ7xtfxCCGoRzGnoi2WNzmJYYJW9BXY, component: SubgraphInstanceManager

Then the writer stops, waits for retry_delay, restarts and we're back to the beginning...

Rewinding the Subgraph fails:
If it helps, when we try to rewind the network subgraph, we're getting:
Pausing deployments ... paused QmSWxvd8SaQK6qZKJ7xtfxCCGoRzGnoi2WNzmJYYJW9BXY[969] ... paused QmSWxvd8SaQK6qZKJ7xtfxCCGoRzGnoi2WNzmJYYJW9BXY[969]
Waiting 20s to make sure pausing was processed

Línea de trabajo
Comienza con el panic de rewind en graph/src/schema/input_schema.rs:822:85 y, después, sigue las rutas de Store y SubgraphInstanceManager mencionadas en los logs. Investiga el fallo de la constraint de la fuente de datos offchain no determinista y su interacción con el determinismo de fulltext-search. Se considera terminado cuando el subgraph deja de fallar repetidamente y su rewind se completa correctamente.
