How get embedded diagrams when accessing a page via Confluence REST API?


A diagram on a page used to be an embedded, base64-encoded png in the body.export_view of a page, e.g:


Old Response

"id": "123456789",
"type": "page",
"status": "current",
"body": {
"export_view": {
"value": "<img class=\"drawio-diagram-image\" src=\"data&colon;image/png;base64,c0debabe..."


But since a recent upgrade of the plugin (8.5.1 -> 9.2.6), I get a useless JS code block for every diagram on a page

New Response

"id": "123456789",
"type": "page",
"status": "current",
"body": {
"export_view": {
"value": "<span id=\"drawio-macro-content-cae9a5a5-bb84-4eba-83d2-b2f5798cf226\" style=\"position:relative;display:inline-block;max-width:100%;overflow:hidden;border:1px solid transparent;\"></span>\n\n<script type=\"text/javascript\">\n(function()\n{\n\t$ = AJS.$;\n\t\n\tvar graphContainer = document.getElementById('drawio-macro-content-cae9a5a5-bb84-4eba-83d2-b2f5798cf226');\n\tvar DrawioProperties = { contextPath : AJS.contextPath() };\n\t\n\tvar readerOpts = {};\n\t\t\treaderOpts.loadUrl = '' + '/rest/drawio/1.0/diagram/crud/..."


Is there any way to replace the JS code block with e.g. link to the rendered diagram?
(Maybe a configuration option for the plugin?)

Theoretically I could parse the JS script block and use the properties of readerOpts to construct the link to the rendered diagram that's available as attachment on the page anyway, but I really don't want to go down that rabbit hole.

Are you sure it's a change to the plugin and not a Confluence update that caused the change?

Reasonably sure, yes. (I'm only a user of this particular confluence server, not an admin)

The change of the output format directly coincides with the plugin update.

I was able to dig up the previous version: 8.5.1

Any chance to get the old behaviour back?

We have implemented an admin setting which will act as a switch. Default will be 1 which will embed the diagram in the output.

It will be in the next release. 

that's great to hear!

Looking forward to the next version, so I can remove the JS script block parsing again...

Any ETA on the release?

Is this fix in 9.2.8?

It is. Search for 'emailpreview' in the docs here.

it's version 9.1.

after setting emailpreview=1, the export_view is still js code.

how to rollback to base64 encode images.image.png

9.1 is too old, you need to update to get the change.
