Errors in importing project

Hello friends,

@loginerror, @Palaniyappan,
I’ve imported a project to a pc with Studio 2019.10.3
I get this error

File ‘Login_Import.xaml’ - variable ‘Pagina_browser’: Type ‘ui:Browser’ (‘’) could not be resolved and was automatically replaced with ‘UnknownType’

How to solve it?

Thank you

delete the .json file from the project folder, then open the main again

click on manage packages and you should be able to reconstruct the packages…

I’m importing the older versions
I get this error

What should I do?
thank you

Opening a project via main.xaml file will throw activity error if they are not part of the default activity imports of UiPath.
Did you try opening the project from project.json file. That will install all the activities before loading the project in editor.

Thank you @nandish47,

how to dothat?


Is the project imported with Project.Json file along with Main.xaml as zipped folder

Cheers @CamiCat


I’ve imported it as a folder.
Which activities and stepd do you mean?

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Make sure that we have the same project dependencies version in both the studio
Go to design tab -> manage packages and there in project dependencies the packages must be of same Version
