Graph model renders fine, but its XML does not contain the style attribute (the graph.getModel() shows undefined styles) #413

Hello

I am trying to export the modified orgchart example by using your export server that has its repository there: https://github.com/jgraph/draw-image-export2

The question is how do I prepare the XML value for this, because I want to keep the gradients exported.

The first attempt I did was to use the https://jgraph.github.io/mxgraph/docs/js-api/files/util/mxImageExport-js.html codec, but this returned a 500 error after a long time of doing "something" (I suspect a timeout). I suspect that this is just wrong to use that method.

The second attempt I did was to use the XML retrieved from mxCodec like in the first example of: https://jgraph.github.io/mxgraph/docs/js-api/files/io/mxCodec-js.html This returned me pure black and white representation of my model without fixing the cell size to its content (no colors, no gradients, no styling).

I am missing something about that XML format, the draw.io page uncompressed XML consists of styled tags like mxGraphModel root mxCell or mxGeometry but mine seems to be more-like simple SVG.

How to get exported XML string with styled elements?

Edit: I noticed that my graph model have undefined styles, i made a screenshot and attached to the issue undefined

Edit2: The graph.getStylesheet() shows the model colours but how do I merge both graph.getModel() and graph.getStylesheet() ?

Edit3: I am actually doing the same thing that happens in the official draw.io source code https://github.com/jgraph/drawio/blob/88af133d284167e1fb9230fb0e45454474074d67/src/main/webapp/js/mxgraph/Dialogs.js#L1454
