Hello all,


the problem me and my colleagues encountered is that whenever some of us go into the Documents module, select a document and we click the "Info & tags" button, we get the following error:

Odoo Client Error

UncaughtClientError > TypeError

Uncaught Javascript Error > Cannot read properties of null (reading 'scrollIntoView')

Occured on demo4.odoo.com on 2025-02-17 12:29:05 GMT

TypeError: Cannot read properties of null (reading 'scrollIntoView')

at MutationObserver.<anonymous> (https://demo4.odoo.com/web/assets/37b7e9d/web.assets_web.min.js:24030:291)

This was tested on our test database, on a publicly available test database and it's all the same.
The only interesting thing we found, is that on my computer this doesn't happen while it does on the computer of my colleague. We also tried different browsers and the results are the same.

Another thing we tried is I logged into my colleague's user on my computer and the error doesn't show up.

The JavaScript error you're encountering in the Odoo 18 Documents module—specifically, the TypeError: Cannot read properties of null (reading 'scrollIntoView') when clicking the "Info & Tags" button—is a known issue reported by multiple users. This error appears to be linked to the MutationObserver in Odoo's JavaScript assets and may be influenced by specific user environments or configurations.

 Potential Workarounds

  1. Clear Browser Cache and Try Different Browsers:
    • Sometimes, cached data can cause unexpected behavior. Clear your browser's cache and cookies, then reload the page.
    • Test the functionality in different browsers to see if the issue persists.
  2. Enable Developer Mode and Check for Errors:
    • Activate Developer Mode in Odoo to gain more insights. Navigate to Settings > Activate Developer Mode.
    • Check the browser's developer console for any additional error messages that might provide more context.
  3. Update to the Latest Odoo Version:
    • Ensure that your Odoo instance is updated to the latest version, as patches and bug fixes are regularly released.
  4. Report the Issue to Odoo Support:
    • If the problem persists, consider reporting it to Odoo's support team or checking their forums for any updates or patches related to this issue.

The Cannot read properties of null (reading 'scrollIntoView') error in Odoo 18’s Documents module occurs because JavaScript tries to call scrollIntoView on a non-existent DOM element, likely due to timing issues or client-side differences. To fix:

  1. Clear browser cache/cookies on your colleague’s computer (rm -rf ~/.cache/chromium/*).
  2. Enable debug mode (?debug=assets) and check the Console for detailed errors.
  3. Compare browser versions, extensions, and system settings between computers.
  4. Add a null check in the JavaScript (if you have source access):
    javascript
    Sao chép
    const element = document.querySelector('.o_inspector_panel'); if (element) element.scrollIntoView();
  5. Disable custom modules to rule out interference.
  6. Wrap code in DOMContentLoaded to ensure DOM readiness.
  7. Report the bug to Odoo with traceback details.
  8. Use --disable-cache-and-cookies and --disable-captive-portals in Catsxp for stable access to demo4.odoo.com.
