An internal error has occurred. It is recommended to restart UiPath Studio.

Hi,

Can you restart your studio and see if it’s happening again, if it’s happening you can import system.text.revularexpressions and work with regex.

Hi,
I have restarted studio and it is happening again. I have installed system.text.regularexpressions but it still return the same error

Hi,

If you want to work with regular expressions, then import namespace system.text.regularexpressions and then you can use regular expression methods.

can you update studio to latest release, first of all?
and use system pack 19.2
also, change to clasic theme, not dark theme and try again

Hi
The name system.text.regularexpressions is already imported but any time when I try to configure regular expressions using Regex builder it shows that error.

Hi
Updating to Studio 2019.2.0 solved this issue. It works with dark theme as well. Thank you
