How to transform requests with chunked Transfer encoding header

[vlntsolo]

Hi there,
I'm trying to integrate Django app running in WSGI mode with external service, which sends callbacks from Java server adding Transfer-Encoding: chunked header. And request body starts with chunk size number:

275
{"id":"XXX", errorCode":null}
0

Django is unable to handle http 1.1 requests. So I figured it can be transformed with buffering in Traefik confg.
I've tried adding the following labels to Traefik proxy config with no luck.
"traefik.http.routers.app.middlewares=request-buffering"

Is there a proper way to do it in Coolify dashboard? I'd appreciate any hints. Thank you!
