webdav issue on PUT

Start by reproducing the PUT request against the docker-library/httpd image based on Debian bookworm, then inspect the Apache logs around /var/lib/dav/DavLock and the reported /po.txt.lock path. Check the installed APR and APR-util packages and the WebDAV lock configuration; done means identifying the cause of the 400 response and documenting a confirmed fix or required configuration.

Hello, I'm running a webdav server using this image http:bookworm as base.

When I try to PUT a file with:

curl -T po.txt http://myserver.me/dir/

I get:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not understand.<br />
</p>
</body></html>

And the log from the server is:

When I created the image I installed the apr and aprutil packages with this line:

apt-get install -y libtool libaprutil1-dev libapr1-dev libaprutil1 libapr1

I saw the line BDB0004 fop_read_meta: /var/lib/dav/DavLock: unexpected file type or format may be linked to this issue, but I'm on debian bookworm.
Any hint about what may be the problem?
Thanks
