Cannot find module "sunburst"

[WillForrestMindBridge]

Affected node export version: 4.0.2, 5.0.0

Highcharts versions tested with node export server: 10.3.3 , 11.1.0

Problem:

When exporting a sunburst chart, the module for sunburst.js is not found, even though it has been cached by highcharts export server.

Indications that this is a node export bug:

• The manifest file (node_modules/highcharts-export-server/.cache/manifest.json) has sunburst listed:

{"version":"11.1.0","modules":{"highcharts":1,"highcharts-more":1,"highcharts-3d":1,"exporting":1,"price-indicator":1,"draggable-points":1,"export-data":1,"hollowcandlestick":1,"xrange":1,"timeline":1,"sankey":1,"gantt":1,"treemap":1,"windbarb":1,"drilldown":1,"boost-canvas":1,"series-label":1,"pyramid3d":1,"marker-clusters":1,"sunburst":1,"item-series":1,"funnel":1,"treegraph":1,"arc-diagram":1,"heikinashi":1,"vector":1,"solid-gauge":1,"tilemap":1,"series-on-point":1,"networkgraph":1,"stock":1,"lollipop":1,"variable-pie":1,"debugger":1,"data":1,"bullet":1,"overlapping-datalabels":1,"static-scale":1,"parallel-coordinates":1,"cylinder":1,"pattern-fill":1,"dependency-wheel":1,"heatmap":1,"pareto":1,"dotplot":1,"variwide":1,"boost":1,"organization":1,"drag-panes":1,"broken-axis":1,"streamgraph":1,"histogram-bellcurve":1,"funnel3d":1,"no-data-to-display":1,"wordcloud":1,"sonification":1,"dumbbell":1,"venn":1,"accessibility":1,"indicators-all":1}}

• The sources.js file in the .cache has the source code for sunburst, and mapping comment is present

//# sourceMappingURL=sunburst.js.map

• The module list is given via a .env file as outlined in the readme.

HIGHCHARTS_VERSION=11.1.0

The standard charts such as stock charts, bar and line charts etc seem to function fine, it's just sunburst that seems to have a module issue at the moment.

Minimum postman payload to have the error occur:

{
    "infile": {
        "chart": {
            "type": "sunburst"
        },
        "title": {
            "text": "Minimal Sunburst Chart"
        },
        "series": [
            {
                "type": "sunburst",
                "data": [
                    {
                        "id": "root",
                        "name": "Root"
                    },
                    {
                        "id": "A",
                        "name": "Category A",
                        "parent": "root"
                    },
                    {
                        "id": "B",
                        "name": "Category B",
                        "parent": "root"
                    },
                    {
                        "id": "A1",
                        "name": "Subcategory A1",
                        "parent": "A",
                        "value": 5
                    }
                ]
            }
        ]
    }
}

This payload works on the older phantomJS export server.

Has anyone else had issues with sunburst charts?

Update / Workaround

I've found that commenting out all the .env variables, and re-downloading the modules on every boot fixes this problem.

This is however problematic, as we use highcharts in a cloud environment, which can have many containers running it.

Using the module list to cache the modules prevented many GET calls to highcharts.

[WillForrestMindBridge]

I've figured it out.

The HIGHCHARTS_MODULE_SCRIPTS loads the modules in the order that they are input. Using the manifest.json in the .cache is tricky, any mistakes in order can be a problem.

Apparently, some modules don't load unless their dependent modules are loaded first. This leads to the failure to load the sunburst module.

The correct order of modules for 11.1.0 is:

stock, map, gantt, exporting, parallel-coordinates, accessibility, boost-canvas, boost, data, data-tools, draggable-points, static-scale, broken-axis, heatmap, tilemap, tiledwebmap, timeline, treemap, treegraph, item-series, drilldown, histogram-bellcurve, bullet, funnel, funnel3d, geoheatmap, pyramid3d, networkgraph, overlapping-datalabels, pareto, pattern-fill, pictorial, price-indicator, sankey, arc-diagram, dependency-wheel, series-label, series-on-point, solid-guage, sonification, streamgraph, sunburst, variable-pie, variwide, vector, venn, windbarb, windcloud, xrange, no-data-to-display, drag-panes, debugger, dumbbell, lollipop, cylinder, organization, dotplot, marker-clusters, hallowcandlestick, heikinashi, flowmap, export-data, navigator, textpath

Could this behaviour at least be documented?
