Getting Error "ERR error getting the content length" if I try to create a markdown or plain text file
Describe the bug
Hello :)
Environment: fresh opencloud deployed via docker compose behind a reverse proxy without collaboration enabled ( COMPOSE_FILE=docker-compose.yml:external-proxy/opencloud.yml ).
Deployment works fine, I even can upload files without any problems, but if I try to create a plain text file or markdown file with the UI, I get the following error in the UI:
X-Request-Id: 3fcad325-dcba-499e-8c6f-a15637cde823
The logs state the following error:

Hello, thanks for the report!
Which reverse proxy are you using? Maybe the issue is there — because using our default proxy, COMPOSE_FILE=docker-compose.yml:traefik/opencloud.yml, works fine for us.
I see the same error message when trying to upload a file with DavX5 using Android Storage Access Framework. Content-Length is 0 in this case. Using wireshark, I confirmed that the incoming request from my reverse proxy (traefik FWIW) to opencloud contains Content-Length: 0, whereas the error message by ocdav suggests that the Content-Length was an empty string. So this seems to get changed by the proxy or some other service of opencloud.
Inside the container's network namespace, I can see that the failing PUT request to ocdav's port 9350 contains a valid Content-Length: 0 header.
I'm not trying to upload an empty file btw., but this happens when DavX5 doesn't know the file size in advance, i.e. when it's uploading a stream. Uploading files with known sizes works as expected. But uploading an empty file may cause the same behavior (haven't tried that).
