Since updating to windows: Expression Activity type 'VisualBasicValue`1' requires compilation in order to run. Please ensure that the workflow has been compiled

[dr1992]

Hey,

I have a variable called ‘pManufacturer’ which can potentially contain accented letters. I previously had in place the following which I could use to replace these, however, since updating to windows, I seem to be getting a VisualVasicValue’1 error (see title).

The string:
System.Text.Encoding.GetEncoding(“ISO-8859-8”).GetBytes(pManufacturer)

I’ve replaced the double " " as suggested by other topics here, but no luck. I have also tried using ‘1251’ instead (as suggested elsewhere). No luck.

Anything I can do to remedy this? Perhaps I am missing some import or dependency (though I don’t think so).

Thanks in advance.

Hi @dr1992

Check out the thread.

Migrated Small workflow from legacy to Windows - I regret this so much

maybe following helps: About the shown statement: As string will be constructed to get it parsed into a datetime which is later returned as a string in (“MM/dd/yyyy”) format. DateTime.Now.ToString("MM/dd/yyyy") will do the same

Please check that all double quotes are fine.

Hmm, so it seems ‘UiPth.CognativeActivities’ isn’t compatible. Is there any alternative I can use for this?

is it possible for you to share the XAML and project.json with us?

I’ve resolved this issue now, after removing the debunked package and imports, I had to use an 'invoke method to get the code to work.
