API: UpdateCustomAttribute: Slim Application Error

[barrisa]

Hello all,
I am currently running Booked 2.7.8 ontop of PHP 5.4.16 on RHEL 7.7.
I am trying to set up a method of updating an attribute's 'possibleValues' field using a bash script (curl) and the Booked API, but keep getting this error:
Slim Application Error: The application could not run because of the following error: Code: Message: trim() expects parameter 1 to be string, array given File: /var/www/html/booked-2.7.8/Domain/CustomAttribute.php Line 477

The command I have executed is:

Code: Select all

$ curl -k -d '{"label":"Release","type":"3","categoryId":"1","regex":"","required":"1","possibleValues":["entry1","entry2"],"sortOrder":1,"appliesToIds":[],"adminOnly":0,"isPrivate":false,"secondaryCategoryId":null,"secondaryEntityIds":[]}' -H "Context-Type: application/json" -H "X-Booked-SessionToken: [session-token]" -H "X-Booked-UserId: [userID]" -X POST https://localhost/booked/Web/Services/index.php/Attributes/4

What is weird is when I don't supply the '4' at the end of the URL, it creates a new attribute perfectly fine. Am I doing something wrong?

Stack:
