How can I verify that my test node is operating correctly? Why am I unable to call contracts after connecting my wallet?

I’ve performed a health check using GraphQL, and it seems to be normal.

{
  "data": {
    "health": true
  }
}

However, I want to confirm how long it takes for the block synchronization. It has been 2 hours since I completed the setup. Currently, when I query for the latest block height, it shows:

{
  "data": {
    "blocks": {
      "nodes": [
        {
          "id": "0xb1807ca9f2eec7e459b866ecf69b68679fc6b205a9a85c16bd4943d1bfc6fb2a",
          "transactions": []
        }
      ]
    }
  }
}

PS:
I tried to call a contract I wrote using the Fuel wallet, but GraphQL threw an error and did not return any response.

@luz33c perhaps share the error you mention was raised by GraphQL
