Open old project

[Dion]

Hi,

I am opening an old project that is still working through invoke workflow. When I opened the Xaml UiPath told me to update the dependencies so I did. This is what I ended up with

When I try to close UiPath I get this error:

I have tried to start the project after deleting the json but that was not the solution.

Can anyone help?

Thnx.

Greeting Dion

@Dion,

Please take the back up of project.json file and delete it in project folder. Then try installing all the packages and then open the workflow. I hope that will solve

[Dion]

I have tried that. It was not the solution.

The strange thing is that it works through invoke workflow, so in the framework it works.

@Dion
We had a similar problem once. It was caused by there being an extra space in one of our conditions, so instead of var1 = 4 we had var1_ = 4 (extra space underlined) and this was causing the exact error you are describing. Try opening your xaml in a text editor and search for double spaces and see if any occur.

Allowing a double space in a condition was a prrevious bug that has been patched out of UiPath in newer versions.

[Dion]

Yes! That’s it! I have edited my workflows en I can open them again.

You are my hero of the day!
