Above error is causing three dot in >>

3. Horizon missing fields in list_traces function , bad calling engine.list_traces:

-fields = ['base_id', 'timestamp', 'info.request.path']
+fields = ['base_id', 'timestamp', 'info.request.path', 'info']

-traces = engine.list_traces(query, fields)
+traces = engine.list_traces(fields)

4. Horizon python3 binary issue :

TypeError at /project/

I will fill also horizon bug and add url to comment.
