ashish32678 opened a new issue, #2106:
URL: https://github.com/apache/incubator-kie-kogito-examples/issues/2106
### Describe the bug
**Steps to reproduce**
1. Set a non-default root path with quarkus.http.root-path=/lifewf
2. Trigger an instance for <PROCESS_ID>
3. Execute the request to get the SVG of the Process Instance (replace
<PROCESS_INSTANCE_ID> with the id returned from the previous request in step 2):
curl -X 'GET' \
'http://localhost:8080/lifewf/svg/processes/NewBusinessProcess/instances/13fd1e60-5a2e-45ea-89e8-3e1463380065'
\
-H 'accept: */*'
Environment
### Expected behavior
SVG of <PROCESS_INSTANCE_ID>
### Actual behavior
{"message":"Cannot invoke \"java.util.List.stream()\" because \"nodes\" is
null"}
