Invoke Method not working in 2018.3.0 community version release

[Sayan]

Hi All,

I have developed a bot to unzip the files using the solution in Enterprise Edition 2018.2.3 and is working totally fine.

However, when the same bot is running in community version 2018.3.0 it is giving the error :

Source: Invoke method

Message: Could not load file or assembly ‘System.IO.Compression, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Exception Type: System.IO.FileLoadException

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.IO.FileLoadException: Could not load file or assembly ‘System.IO.Compression, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ or one of its dependencies.

Is it something related to the version 2018.3.0? Or is there any way around this?

Please Help!

This is something only UiPath support team can answer.

If its not too late.
Here is what you do.

Open your workflow and then click on Import
Then in the text box enter the namespace ‘System.IO.Compression’ and select it. Save and nownyou should be good to go
