422 resposne for querying

Hi, I am trying to query the api for some data which I have on your service.

My url looks like this:

"https://{_mysubdomain}.zendesk.com/api/v2/search.json/export?query=type:user created_at>{_somedate}

Which should give me a lot of users

I then get a lot of users, a 100 at the time of them, and I then iterate through the paginated response.

When I get to page 11, I get a 422 response. Just like in this  question.

The answer to the question here seems  to be to use something called "incrementtal exports"   but I could'nt find notes about how to mitigate my issue in the linked docs.

This link was however also posted, where it looks like I can do queries with more than 1000 results with this endpoint:

GET /api/v2/search/export?query={query}

and about this endpoint is written:

This endpoint is for search queries that will return more than 1000 results. The result set is ordered only by the created_at attribute.

So I tried:

{_subdomain}.zendesk.com/api/v2/search/export/?query=type:user created_at>{_somedate}

However, when I run this endpoint, I am returned a 415, with "unsupported media type", which I'm not a 100 % sure what means.

What needs to be done to be able to pull out my data?
