Note that chunked requests should not be used, or add nginx to Open Klant helm chart (and most likely Objects+ObjectTypes too)

Klantinteracties API

Omschrijving / Description

Currently we use Open Klant with uwsgi-in-http-mode (as most components) however our helm charts are without nginx.

This works, but it does depend on the client not using HTTP 1 chunked requests (KISS did). If a client does then uwsgi will not process the body of the requests and Django doesn't see the contents. This was discovered by Utrecht by Marcel and Jordi, which also depends on which K8s ingress is used because if you communicate via an nginx-ingress or via an nginx pod then the problem doesn't occur (nginx supports chunked requests).

Lets either document this limitation of Open Klant, or (which I would prefer) is ensure that Open Klant and our other components always have nginx in front of them. Our SaaS-installs are set up this way, and we have nginx in our Open Zaak / Open Forms / Open Inwoner charts I'd want to avoid exposing uwsgi-specific restrictions if we can avoid this.
