cannot fix/save sku of product with trailing space

[medigeek]

Preconditions (*)

1. magento 2.4.7-p2
2. magento/inventory-metapackage 1.2.7-p2
3. magento/module-inventory 1.2.5

Steps to reproduce (*)

The issue happens when you already have products pre-existing before the magento inventory leading/trailing space validation check.
The validation system doesn't allow you to change/fix product skus with pre-existing products with space characters.

1. disable/comment out the validation check in Model/Validators/NoSpaceBeforeAndAfterString.php
2. create a product with trailing space character
3. re-enable the validation check in Model/Validators/NoSpaceBeforeAndAfterString.php
4. try to modify/remove the space from the sku of the product and save

Expected result (*)

1. expecting successful product save
2. successfully able to change the leading/trailing space characters

Actual result (*)

While saving you see the error: The stock item was unable to be saved. Please try again.

In the logs this error comes up: Validation Failed: "sku" can not contain leading or trailing spaces.

Add this code in NoSpaceBeforeAndAfterString.php file

if ($trimValue !== $value) {
$errors[] = __('"%field" can not contain leading or trailing spaces.', ['field' => $fieldName]);

    }
