-H "Content-Type: application/json" \
-d '{"token": "$ACCESS_TOKEN"}'

1. Check Token Format

• Verify JWT structure
• Check token encoding
• Validate token signature

2. Token Expiration
   • Check token expiration time

Debugging Tools

​

Log Analysis

logging:
level: DEBUG
authlete: DEBUG
security: INFO
performance: INFO

# Filter error logs
grep "ERROR" /var/log/authlete/app.log

# Monitor real-time logs
tail -f /var/log/authlete/app.log | grep "ERROR"

# Analyze performance logs
grep "duration" /var/log/authlete/app.log | sort -n

​
