Number (Auto-Increments) not working in Opportunity but in Account?

[especial]

Hi fellas, I tried to add a field Opportunity number, which could be automatically updated with Number (Auto-Increments) , I created a field in Opportunity, it doesn't work, it shows 400 error when I was trying to save the Opportunity, but i created "Account number" also with the field type Number (Auto-Increments), it works well, using ESPOCRM 8.4.2, php8.2, any help will be highly apprreciated, thanks.

- Send a screenshot of this field's settings.
- Do you use any formulas, workflows or BPMns for Opportunity?
- Enable Debug mode: https://docs.espocrm.com/administrat...ng/#debug-mode.
- Reproduce the error.
- Submit an error log. EspoCRM log files are located in {ESPO_ROOT}/data/logs/ directory. Most errors are logger there.

P.S. Tested on 8.4.2 for Opportunity both Number (auto-increment) and Auto-increment. Everything works great.
Number (auto-increment) is filled only in records that will be created after this field is created. You will not be able to number old opportunities using this field.
