Config Desktop Services with Veyon-cli

[FrozenApe]

Hi there,
Here my problem : I'm trying to add a PredefinedPrograms by using veyon-cli so I tried to catch the grammar of the settings whitch is something like that :

DesktopServices/PredefinedPrograms=[{"Name":"NewProgram","Path":"c:\temp\test.exe","Type":1,"Uid":"{17768e26-ca24-43dc-9d0d-544481f9f846}"},{"Name":"New program2","Path":"c:\temp\test.exe","Type":1,"Uid":"{9051b94b-c1a0-4269-b2e3-a5695d89a321}"}]

Then when I try to set the settings with veyon-cli config set DesktopServices/PredefinedPrograms=[{"Name":"NewProgrammodified","Path":"c:\temp\test2.exe","Type":1,"Uid":"{17768e26-ca24-43dc-9d0d-544481f9f846}"},{"Name":"New program2modified","Path":"c:\temp\test2.exe","Type":1,"Uid":"{9051b94b-c1a0-4269-b2e3-a5695d89a321}"}]

I get an error : please specify a valide value

Is someone have an idea how to make it work ?
Thanks by advance
