Error: no diagram to display

Users

Hello,

I updated BPMN in my Angular project from version 13.2.2 to 17.11.1. After the update, I’m encountering errors on all of my processes, regardless of whether they are from the original bpmn.io website or my old ones.

The entire project is built on Angular, and everything worked fine before the update. Did I miss something critical, or is this a known bug? Should I consider downgrading?

How are you importing the diagram? You might have to adjust to account for breaking changes: bpmn-js/CHANGELOG.md at develop · bpmn-io/bpmn-js · GitHub

Using modler.importXML method, giving xml and telling what properties to attach

Generally, expect things to break when skipping several major versions and have a look at the changelog to see what breaking changes were introduced. Glad you were able to resolve your problem. :slight_smile:
