Env  
OS: Ubuntu Linux (Container to be exact)  
Python version: 3.10  
Framework and version [e.g. Django 2.1]: flask-3.0.2  
APM Server version: 8.15  
Agent version: 6.23.0

Using all default values.

Agent Setup (code)  
def configure\_apm(wsgi\_app: Flask) -\> None:  
apm = ElasticAPM(wsgi\_app, enabled='TRUE', debug='TRUE')

Agent option  
ELASTIC\_APM\_SERVICE\_NAME : app  
ELASTIC\_APM\_SERVER\_URL : http://  
ELASTIC\_APM\_CAPTURE\_HEADERS : "false"

In a Java application, error lists are displayed properly, but errors are not identified in Python applications only. What should I look for?
