Actual error message:

I would be interested to hear if anyone has experienced the issue raised by Matthew and found a remedy or workaround. We are a vendor that currently has an integration with Moodle where we call the core_course_get_courses method to get all the courses. Unfortunately, for one school, they experienced the same errors as described in this thread.
There is another thread that sort of delves into the possibility to filter the core_course_get_courses call by something like the "category id": https://moodle.org/mod/forum/discuss.php?d=348752
However, it does not appear that any work has been done in that area.
I've since realized there is the core_course_get_courses_by_field method that was introduced in version 3.2. This new method is the replacement for core_course_get_courses.
Here is the syntax to filter by a category value, but you can also filter by id, course id, short name or category:
https://MOODLEURL/webservice/rest/server.php?wstoken=TOKENVALUE&wsfunction=core_course_get_courses_by_field&field=category&value=[###]&moodlewsrestformat=json
Please ensure the new API method is added as a function to the webservice token so you have the proper access.
