Problem/motivation

During our testing for the upgrade to Drupal 10.5.x, we identified a bug that occurs when attempting to update the "Displayed text" of an existing link.

Drupal 10.5.1
Linkit 7.0.6

Uncaught CKEditorError: Cannot read properties of undefined (reading 'attributes')

Steps to reproduce

While I haven’t been able to reproduce the issue consistently, I can trigger the error approximately 90% of the time. Given this frequency, I believe it's worth creating an issue for further discussion and investigation.

  1. Edit an existing link
  2. Try to update the 'Displayed text'

P.S. It seems that appending text doesn’t trigger the error, but replacing the entire text does make it more likely to occur.

    Thanks for reporting this. I am able to reproduce. Specifically, using a generic installation of the Standard profile, adding Linkit to the Basic HTML text format:

    1. Click the "Link" icon.
    2. Enter a "Displayed text" value.
    3. Enter the first character of an existing node and use Linkit's autocomplete to choose a result from the dropdown. Confirm that the internal path to the node is populated in the "Link URL" field.
    4. Quickly(!) Remove the contents from the "Displayed text" input and quickly enter new text and press "Insert."
    5. Link text will not be updated and the console will show the Uncaught CKEditorError: Cannot read properties of undefined (reading 'attributes') error.

    Additionally, this is something else that doesn't work correctly.
    1. Click the "Link" icon.
    2. Enter a "Displayed text" value.
    3. Enter the first character of an existing node and use Linkit's autocomplete to choose a result from the dropdown. Confirm that the internal path to the node is populated in the "Link URL" field.
    4. Now click "Link URL" field again and enter the first character of another node and use Linkit's autocomplete to choose a different result.
    5. The link field will NOT correctly populate the internal path to the node but will simply populate the character you entered.

    I've merged a number of changes related to CKEditor v45 compatibility to reduce the surface area here. The originally reported problem still remains, so this is "Needs work."

    Also had to disable the "Linkit profile" for Ckeditors after updating core 10.5 due to the error "Cannot convert undefined or null to object" in CKEditor 5 caused by a bug in the Linkit module version 6.1.6. Specifically, in the JavaScript file index.js at line 122, the code attempts to call Object.assign(args[2], values) where args[2] can be undefined or null. This occurs when the CKEditor 5 link command is executed with fewer than 3 arguments, but the code assumes the third argument (index 2) will always be an object.

    When title is empty and clicking insert

    @nicholass
    when you're updating dependencies, especially when Drupal is updated, run command to check for any major versions of contrib modules:
    composer outdated -M -D

    composer update usually just updates minor version by default (eg 6.1 to 6.2) if dependency has carrot (^) "drupal/linkit": "^6.0", but not to 7.0
