Pagination incidents endpoint does not work/is badly documented

[sharkwouter]

I can't figure out how this is supposed to work, I'm using the following documentation: https://www.statuspal.io/api-docs/v2#tag/Incidents/operation/getIncidents

I've tried setting before to the starts_at value of the last entry I've received. Using the id also didn't work. Same with just a date. All give me 500 errors. The documentation does not give any information on what kind of value is expected.

What do I do here? Can the documentation be updated?
