Resolved Request is invalid. Error in line 74

[kevinjansen]

Server operating system version

Centos 7.9

Plesk version and microupdate number

Obisidan 18.0.57

Dear,

The Plesk contains a error/problem.
I can see on all our updated servers alot for errors (Change Log for Plesk Obsidian)

The error is:
Parser error: Request is invalid. Error in line 74: local complex type: The content model is not determinist. Original request: <?xml version="1.0"?>

We get this error on a lot of commands. Example:
- Opening Acronis
- Installing automatic wordpress on package creation
- On creating a package with the API
(
{ "code": 1014, "message": "Parser error: Request is invalid. Error in line 74: local complex type: The content model is not determinist." }
)

And it all started this morning around 10:00.
It happends on 18.0.57.x but also on 18.0.56.x the only thing that i currently can see is that it happens on Centos servers (maybe almalinux also) But thats because all our servers are centos based and we do not yet have busy servers running on Almalinux or Debian.

Kind Regards,

Kevin

The issue on our side is/was that libxml got updated to libxml2.2.12
This is a new version since 23-11-2023, after having a talk with Plesk we downgraded the package back and everything was working again.

I think Plesk will come with a update shortly to support libxml2.2.12

We think that the root cause are updated packages libxml2-2.12.1-1.0.cf.rhel7.x86_64 and python2-libxml2-2.12.1-1.0.cf.rhel7.x86_64 from a custom repository "CityFan", that are not supported by Plesk. Are you using that repository?

 

[kevinjansen]

Hi Frank,

This was the solution for our server. Please check the commands and change them for your needs.

sudo rm /etc/yum.repos.d/city-fan.repo
sudo rpm -e --nodeps python2-libxml2
sudo yum downgrade libxml2-2.9.1 libxslt-1.1.28 -y
sudo yum install libxml2-python -y
sudo systemctl restart sw-engine
sudo service plesk-php80-fpm restart
sudo service plesk-php81-fpm restart
sudo service plesk-php82-fpm restart

This was the solution for our server. Please check the commands and change them for your needs.

sudo rm /etc/yum.repos.d/city-fan.repo
sudo rpm -e --nodeps python2-libxml2
sudo yum downgrade libxml2-2.9.1 libxslt-1.1.28 -y
sudo yum install libxml2-python -y
sudo systemctl restart sw-engine
sudo service plesk-php80-fpm restart
sudo service plesk-php81-fpm restart

Hello, I have the same error with the ssl certificates that cannot be opened ssl hit, and the error comes out:
Error: Parser error: Request is invalid. Error in line 74: local complex type: The content model is not determinist.
