UML Diagram & MindMap
It is very important to use flowcharts for document writing. However, Feishu's API currently does not provide flowchart data or images in Feishu Docs. Therefore, all "flowcharts", "mind maps", and "UML diagrams" will be ignored when exporting.
Starting from version v0.7.0, Feishu Pages supports exporting Feishu Artboards without additional operations. Other types such as UML and mind maps still require manual operation.
You can choose to upgrade these old UML and mind maps to a new drawing board in Feishu Docs, which can support export without manually inserting images.
Solution
Insert the images they export after the flowchart or mind map, so that there are images when exporting Feishu Pages.
In the Feishu editor, there is a function to export or copy flowcharts. You can take a look.
In this way, the original flowchart is still in Feishu Docs. If we need to update the content frequently in the later stage, we can continue to modify the original flowchart. After the modification, we can download the image again and replace the exported image behind it.
For example
The following UML diagram
The following is a MindMap:
