Error message

This query took more than 15s to run — which might indicate you're querying too much or have some unoptimized code:\nFile path: ${queryJob.componentPath}

What it means

reportLongRunningQueryJob warns when a page/static/slice query ran longer than 15 seconds. This is a performance signal, not a failure: the query still completes, but it usually indicates an expensive query (deep connections, unfiltered lists) or slow source plugin code, and it can stall the overall build.

Solutions

1. Narrow the GraphQL query with filters, limits, and fewer nested fields
2. Add indexes/cache on the source side or use a faster source plugin
3. Profile the query with `gatsby build --verbose` or QUERY_ROWS_LIMIT instrumentation; split heavy pages into slices
