I get parse errors on deployment of bpmn to the camunda engine from this example: https://github.com/bpmn-io/bpmn-js-examples/blob/master/custom-meta-model/resources/sample.bpmn
How can we make the camunda engine not throw error when encountering extension element? Also want to read all the extension elements as an array with their properties during parse process. Appreciate any help. Thanks.

@mns seems your BPMN model has issues.can you upload your BPMN model?

I believe this can be split up in a number of activities and partly automated.

Oddly enough, if you open the bpmn in file in Camunda modeler and change something insignificant (like Process Name) and re-save it, the process will be deployable. It gets pretty mangled, so I couldn’t quickly identify the exact diff that fixes the issue. That example hasn’t been updated since 2015, maybe there was a slight change in the spec or the validation logic that has changed since then.

@mns , when i copy your bpmn model xml to camunda modeler (latest), i got the below warnings.
Updating the bpmn, should work.
