### Begin of the deletion Background:

I am setting up a Jenkins job/webhook that updates OP work packages once they're identified in our Repo commits.

I am having an issue where a PATCH API call to /api/v3/work\_packages/ returns a 200 response, but the task does not change. If I copy the exact payload from my Jenkins script output, and place it in my /api/docs page to test it, it does do the change.

###End of the deletion Steps to reproduce

_Please write down the steps to reproduce. Try to write down all necessary preconditions (what permissions do you have, are other users involved?). Example:_

1. Set up an environment with a work package that you wish to change via Begin of the insertiontheEnd of the insertion API.
2. Submit a Begin of the deletion GET API request for the Work Package using Basic API key authentication (API Key holder is Project Admin).
3. Get valid response and store the lockVersion value.
