        Update chart query context.

        To load data from the endpoint the chart must have been saved
        with its query context. For charts without saved query context we
        get a screenshot to force the chart to produce and save the query
        context. ``failed_error`` lets the caller surface a format-specific
        failure (e.g. Excel vs CSV) when the screenshot fallback fails.

Solutions

1. Check server logs for the exception while building the report dataframe.
2. Verify the chart's saved query context still runs successfully in Explore.

When it happens
