Facing Technical Server Error in Odoo 18 – How to Diagnose and Fix?

[vihanrichard]

Has anyone encountered a technical server error while using Odoo 18- I'm currently facing this issue during certain backend operations, and it seems to be causing interruptions in workflow. For those who’ve solved similar problems—what steps did you follow to identify the root cause?
Some initial checks I've done:

• Verified Odoo logs (under /var/log/odoo/)
• Checked custom module compatibility post-upgrade
• Cleared cache and restarted the Odoo service
  
  
• Would love to hear if anyone has used advanced debugging (like --dev=all mode), database query tracing, or XML-RPC logs to isolate the issue. Let’s share tips to make Odoo 18 more stable for everyone.
