Troubleshooting insights that show zeros

Problem

An insight returns only today's data or all zeroes, and a warning is displayed for the data series.
'There was an issue during data processing that caused this point to be incomplete.'

Cause

Application errors or limitations.
Infrastructure-related errors, such as disk, memory, or CPU.
Transient processing errors while generating the insight.

Troubleshooting steps

Get the insight's GraphQL ID. Run this in the GraphQL API explorer (/api/console) to list all insights and their IDs


query {
  insightViews {
    nodes {
      id
      presentation {
        ... on LineChartInsightViewPresentation {
          title
        }
      }
    }
  }
}

Use the ID from above in the Admin Debug GraphQL Query
The raw field returns a JSON dump per series containing:
- QueueStatus — counts of queued, processing, completed, errored, failed jobs, plus SearchErrors with actual error messages
- Backfills — backfill state and per-repository errors
- SeriesMetadata — the raw row from insight_series table
```
query {
  insightViewDebug(id: "<paste id here>") {
    raw
  }
}
```
Next steps will be determined from the raw data output above.
Some possible errors include application errors, transient network errors, or infrastructure errors.
Application error example:
[\"revision not found: repo 142557 @HEAD\",\"revision not found: repo 142557 @HEAD\"]},
Infrastructure error example:
[rpc error: code = Unknown desc = failed to get archive: failed to fetch missing archive cache item: failed to copy and close missing archive cache item: write: no space left on device]
