examples sklearn_text_classifier model.py get project_id error

label-studio-ml-backend examples sklearn_text_classifier model.py function fit(self, event, data, **kwargs):
The error in obtaining the variable 'project_id' at line 165 :

× project_id = data['annotation']['project']
│
╰─> should be change to : project_id = data['project']['id']

Open examples/sklearn_text_classifier/model.py and inspect fit(self, event, data, **kwargs) around line 165, starting with how the incoming data is accessed. Update the project ID lookup to match the reported data structure, then run the sklearn_text_classifier example to confirm fit no longer raises the project_id error.
