🐛 I'm reporting a Bug 🐛

Please update to the last available patch for the version.

Here's an example of a Git issue for the latest Akeneo version:

---

Description:
When attempting to create a product model without specifying a model code, an internal server error is generated instead of the expected field instruction indicating that the model code is required.

Environment:

• Akeneo Version: 7.0.66

Steps to Reproduce:

1. Go to the product models section in the Akeneo interface.
2. Click on "Create" to add a new product model.
3. Leave the model code field empty.
4. Fill in the Family field only.
5. Click "Save."

Expected Behavior:
An error message or field instruction should be displayed indicating that the model code is a required field as working in the initial condition.

Actual Behavior:
An internal server error is generated, preventing the creation of the product model and not providing the user with the necessary feedback about the missing model code.

Screenshots:

Logs:

Please find the relevant logs or error messages.

Additional Information:
This issue prevents users from correctly identifying the problem when the model code is not provided, leading to confusion and potential data entry issues.
