Steps: - Go to "Website" > "Go to Website" - Click Edit in the top right corner - Click Options - Select "Add a Google Font" in the Font Family field - Insert an erroneous Google Font link (e.g. https://fonts.google.com/specimen/Robotoj ) - Save & Reload - Click Edit again Bug: The Edit button is not responding anymore Explanation: We try to `@import` the link in multiple files. For example, here: https://github.com/odoo/odoo/blob/70eb39b0cf30c1acf9a7116e109874b60e27aa2c/addons/website/static/src/scss/website.scss#L10 An erroneous font family results in an error 400 from the Google Fonts server. This prevents parts of the JS to load and makes it impossible to enter the edition mode. `EditPageMenu` handles the behavior when clicking on the Edit button. This menu depends on `website.compiled_assets_wysiwyg` as seen here: https://github.com/odoo/odoo/blob/b02a99bec709b5a6dc4dabb6cb81435dadc24e7e/addons/website/static/src/js/menu/edit.js#L10-L14 Since there is an error generating the file, the Promise fails but the error is not handled: https://github.com/odoo/odoo/blob/70eb39b0cf30c1acf9a7116e109874b60e27aa2c/addons/web/static/src/js/core/ajax.js#L164-L168 This commit prevents CSS loading errors from silently failing. The crash screen will only show up if the user is logged in and has edition rights. This commit also prevents the user from posting the form if the font is not accessible. At the moment, querying an unknown Google font from a script will result in a CORS error. A valid one will pass just fine. In case Google changes the behavior of these queries and allows the 400 to be sent, the fix also checks if the query returned an `ok` status code. opw:2439073 closes odoo/odoo#64824 X-original-commit: 604c07edcd4da8cf2a663d06ba91f137eb74691b Signed-off-by: backspac <backspac@users.noreply.github.com>
