Graph Indexer Issue

[oselezi]

I'm getting a issue after closing allocations. I'm not sure if it's related to the new operator because I've changed it

Now I'm pointing directly to the thegraph endpoint to avoid my network subgraph but I'm getting the same error
but some queries run well and others bad. Not all queries.

I believe the way this works is that both indexer-agent and indexer-service will monitor the status of the INDEXER_AGENT_NETWORK_SUBGRAPH_DEPLOYMENT deployment by checking with your index-node (defined by INDEXER_SERVICE_GRAPH_NODE_STATUS_ENDPOINT). Until that subgraph is synced, it'll fallback to INDEXER_AGENT_NETWORK_SUBGRAPH_ENDPOINT for queries against the network subgraph, but once it is synced, it will use the local deployment instead. The same is true for indexer-service (with the respective env variables).

INDEXER_AGENT_SERVE_NETWORK_SUBGRAPH is a legacy approach, which had indexer-agent implement the proxy and fallback for the network subgraph at /network, and then have indexer-service consume the local network subgraph via indexer-agent. However, this creates a hard (query-serving path) dependency on indexer-agent and therefore this approach was deprecated in favour of allowing both indexer-agent and indexer-service to both independently monitor the local deployment and implement failover to the gateway endpoint.

tldr;

Set indexer-agent environment:

INDEXER_AGENT_NETWORK_SUBGRAPH_ENDPOINT=https://gateway.thegraph.com/network
INDEXER_AGENT_NETWORK_SUBGRAPH_DEPLOYMENT=Qmf5XXWA8zhHbdvWqtPcR3jFkmb5FLR4MAefEYx8E3pHfr

Set indexer-service environment:

INDEXER_SERVICE_NETWORK_SUBGRAPH_DEPLOYMENT=Qmf5XXWA8zhHbdvWqtPcR3jFkmb5FLR4MAefEYx8E3pHfr
INDEXER_SERVICE_NETWORK_SUBGRAPH_ENDPOINT=https://gateway.thegraph.com/network

Do not set INDEXER_AGENT_SERVE_NETWORK_SUBGRAPH or INDEXER_SERVICE_SERVE_NETWORK_SUBGRAPH.
