Hi, guys,
after upgrading and downgread installed Uipath.System.Activities packages I cannot get rid of csv error:

Read CSV: Method not found: ‘Void CsvHelper.CsvParser…ctor(System.IO.TextReader)’.

Any advice, how to solve it?

which version would be worked?

give a try also on updating the UiPath.Excel.Activities

Take a Backup of the entire Project/Xamls before doing this

Hi

Have a view on this similar thread and solution

Read CSV: Method not found: 'Void CsvHelper.CsvParser..ctor(System.IO.TextReader)'

In summary, packages that you downloaded, may contain dependencies you had already used. And if there are duplicate dependencies, the package with the latest version overrides the older one. Hey, This problem occurs because there is one more CsvHelper package in IntelligentOCR.Activities as you see in the picture. [csvhelper] But this problem only occurs in the 4.9-preview version. If you downgrade to 4.8-preview you will be able to use CSV methods. Also, you can downgrade to stable version…

And also try uninstalling if any Salesforce Package installed and work with CSV activity

we would recommend to focus on the issue to get it sorted out. Maybe UiPath Tech Team will also be looped in.

In case of urgent delivery need we can do following workaround:

• read text file
• generate datatable activity and parsing the csv data into a datatable

Thank you very much for your quick reply.

I thought it maybe the problem of Uipath.System.Activities package.
it turns out that this error resolved by also updating the UiPath.Excel.[Activities]

Thank you very much!
