Conan hosted repository not working

[f18m]

What are you trying to do?

I would like to host my own Conan repository in my Nexus. I'm using NRM OSS version 3.22.1 and I have enabled in the "nexus.properties" file the setting "nexus.conan.hosted.enabled=true". I was able to create a hosted repository in Nexus and I configured it in my "conan 1.29.0" client. However the upload of any package to my hosted repository always fails with an error like

ERROR: openssl/1.1.1g: Upload recipe to 'nexus_nossl' failed: invalid literal for int() with base 10: ''. [Remote: nexus_nossl]

Procedure to reproduce the problem

1. on my Linux client I generated a "conanfile.txt" containing:

[requires]
openssl/1.1.1g

2. I download from "conan-center" such Conan package by running "install" command against the conanfile.txt generated in step 1; this of course works:

# conan install .
Configuration:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Release
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=8
os=Linux
os_build=Linux
[options]
[build_requires]
[env]

3. I try to re-upload such package (not created by me so I assume the package is just fine as it's hosted and works fine on the Conan center) on my Nexus hosted repository:

# conan remote list

# conan user -r nexus_nossl developer

Same issue if I try to upload against my Nexus hosted repository having SSL check disabled:

# conan upload -r nexus_nossl openssl/1.1.1g
Are you sure you want to upload 'openssl/1.1.1g' to 'nexus_nossl'? (yes/no): yes

ERROR: Errors uploading some packages

4. note that the upload works just fine if instead of uploading to Nexus I upload that package to an Artifactory repository I have access to:

# conan upload -r artifactory openssl/1.1.1g
Are you sure you want to upload 'openssl/1.1.1g' to 'artifactory'? (yes/no): yes

Uploaded conan_sources.tgz -> openssl/1.1.1g [0.46k]

Uploaded conanmanifest.txt -> openssl/1.1.1g [0.17k]                                     
Uploaded conan recipe 'openssl/1.1.1g' to 'artifactory': https://empirixartifactory.jfrog.io/artifactory/api/conan/conan-local/

So the problem has to be on the Nexus hosted repository implementation...
