Error in Control Panel backup

onlyoffice-workspace 12.7.1.1942 deb packages via install-debian script upgrade
controlpanel 3.5.4.54
Ubuntu 18.04

When I try to run a backup in controlpanel i get the following error:

ASC.Api.ApiSetup - method error: http://127.0.0.1/api/2.0/portal/getBackupProgress.json - Server error System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: Method not found: void ICSharpCode.SharpZipLib.Tar.TarOutputStream…ctor(System.IO.Stream,System.Text.Encoding) (Fault Detail is equal to Method not found: void ICSharpCode.SharpZipLib.Tar.TarOutputStream…ctor(System.IO.Stream,System.Text.Encoding)).

Also seeing this in svcBackup.log not sure if related:

Hello @ronm,
Please check the Mono version (mono --version command), please show us the output result.

Mono JIT compiler version 6.12.0.90

Hello @ronm
There’s strict dependency to the Mono v.6.8.0 on the side of Community Server.
It seems that the situation is related to your current Mono version. If you are able to roll it back to v.6.8.0
