Docker: invalid JSON: json: cannot unmarshal string into Go struct field HostConfig.HostConfig.Ulimits of type units.Ulimit

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk Obsidian 18.0.66 Update #2
Web Pro Edition
AlmaLinux 8.10 (Cerulean Leopard)

PROBLEM DESCRIPTION

Updating the Docker settings via the Plesk interface after Docker has been started through the CLI results in the error:

'invalid JSON: json: cannot unmarshal string into Go struct field HostConfig.HostConfig.Ulimits of type units.Ulimit'

STEPS TO REPRODUCE

Start Docker via the CLI with the required Ulimit configuration:

#docker run --name=varnish-2 --ulimit memlock=-1 -p 127.0.0.1:32782:80 -p 127.0.0.1:7443:8443 -v /root/varnish/conf:/etc/varnish/ varnish:7.6.1

Then, go to the Plesk interface and try to update the 'Automatic start after system reboot' setting for this Docker container or any other setting

ACTUAL RESULT

Error Message: "invalid JSON: json: cannot unmarshal string into Go struct field HostConfig.HostConfig.Ulimits of type units.Ulimit" is displayed.

The setting will not be updated.

EXPECTED RESULT

Settings to be successfully updated.
