Bug Report: Error During Combat Sequence

Description: During a combat session, I rolled for initiative and it was my turn to attack, following the D&D ruleset. After describing my attack, I waited for Franz's response, which required my confirmation. However, upon submitting my action, an error occurred prompting me to file a bug report.

Potential Cause: The session originated a few months ago, which may suggest compatibility issues due to recent updates.

Steps to Reproduce:

1. Enter combat and roll for initiative.

2. Describe attack according to the D&D ruleset :
   "I invoke the rune to summon fiery shackles on my sword : the target takes an extra <strong>2d6</strong> fire damage as a bonus action.I also use Action Surge to have an extra action. So 3 attacks on the Yochlol"

3. Await and receive input from Franz.

4. Confirm actions and submit.

Expected Result: The attack action is processed without errors.

Actual Result: An error occurs upon submission, preventing action completion.
