Sometimes API returns erroneously empty list of edges

[vporton]

Sometimes request

query {
  transactions(
    first: 1
    tags: [{ name: "Content-Type", values: ["text/pdf"] }]
  ) {
    edges {
      cursor
      node {
        id
        owner {
          address
        }
        tags {
          name
          value
        }
      }
    }
  }
}

is responded with erroneous "edges": []

{
  "data": {
    "transactions": {
      "edges": []
    }
  }
}

This seems completely random when edges are erroneously reported empty.

docker-compose did not crash during this bug happening.

Note that repeated (the same) requests return the same erroneous result.

Neither

docker-compose restart server

nor restarting docker-compose
solve the problem (that is does not change the returned response).

Also note in the past I had many "not enough disk space" errors inside the postgres Docker container (due to misconfigured Docker).

Maybe these "not enough space" in the past caused this bug in the present? Should I delete the data and start syncing the DB anew?

Oh, it should be application/pdf, closing.

I reopen the bug:

I read several HTML files "in chain" passing the cursor value from the previous query to the next query. And it produces a list of just three files, despite I have many. This seems to happen only from time to time. It is a serious bug.

I do the following three requests in order, with no request (at least if no hacker intervened) in-between.

Note that I changed the spacing below.

    first: 1,
