Chart extension do not display after updating page content through rest api

Thanh Lam_6rygoa

I am using python to format data point into a Confluence storage format and update the page through REST API. The request did go through and it updated the table content but the chart is not displaying.

I am getting this message from the update confluence page:

                No data to display

We can’t find this chart’s source table on the page.

When I go to editing mode, the chart display correctly, and the Update button show up even though I did not make any editing after sending the update request. I update the page and now the page is update. What is causing this issue? and how can I fix this?

Please help

Thanks,

Hi @Thanh Lam

Looks like it is due to how the macro processes its source table.

It may due to its dynamic binding to a data source, such as a table, in the Confluence storage format. When updating the page content via the REST API, the macro may not properly reprocess the data source until a manual update is triggered in the editor.

You can give a try by programmatically trigger a page re-render after updating the page through the REST API. This can be achieved by using one of two approaches: updating the page twice with minor modifications to trigger a re-render, or simulating the behavior of editing and saving the page using the Confluence API, which involves retrieving the page content, updating it as needed, and updating the page properties to trigger a full re-render.

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Hi VJ,

I did try the method of getting back the body storage of the updated page, append new content under the old content and update it again. The new content did show up but the chart still not render. Not sure what I am missing in the html content.

Hi @Thanh Lam

First, ensure that the HTML structure of your table is correct and sticks to Confluence's storage format requirements.

Also, verify that the chart macro is configured correctly and is pointing to the right data source.

Besides, confirm that you are incrementing the version number in your API request, as this is crucial for Confluence to recognize your update as a new version. If possible, consider moving your data table to a separate page and using the Page Include macro to reference it in your chart page.

You can also try using a simplified version of your table with static data to see if it renders correctly.

Best Regards

Hi @Humashankar VJ ,

I created the table and chart manually on a separated page and get the body storage of that page to compare with the HTML structure that I generated from my script. The output look identical and the weird thing is that I even try to use to html that I got from the manual to update on a new page, it still not render. I am trying to use the chart plotting by confluence instead of chart macro (the look is better). As for the version number, I do update it every time i update the page.

@Thanh Lam - Thanks for confirming, hopefully you can also ensure all the tags closed correctly with the required parameters. Atlassian Document Format

The incomplete structure may be contributing to the issues with chart rendering after API updates.

@Humashankar VJ - I double checked, and all the tags closed properly.

Thanks @Thanh Lam for confirming.

Let me take some time to analyze what other options would have causing the issue. Will keep you posted.
