Json just disappeared, Can't open xaml. Invalid File

HsDev · June 21, 2019, 8:49pm

Everything on my Xaml was working great until I changed a URL, which I suppose may have had some sort of invalid char in it or something? Either way, I am no longer able to open the the script. I’m getting an error message about the Json, so I opened up the Json and there isn’t anything in there. It’s just a blank text file. before this started happening I was getting a message that it was an invalid file. I’m confused, because the only thing I changed, was the URL, and I deleted a couple of click activities, and replaced it with a navigate to activity, with a different URL. Here is the current error message:

Did you try deleting the .json file so it can be regenerated, or copy one from another project and edit the name/description?

HsDev · June 21, 2019, 9:16pm

I have not tried that. I was thinking about it, but I wasn’t sure. I didn’t want to further create any more problems.

HsDev · June 21, 2019, 9:27pm

The Json did regenerate, so that’s all good, but now I’m getting this error… And that the document is invalid.

Open Document Error:

I am not sure to be honest. Do other xaml files open? If so, copy their .json file to the other project and see if it gets resolved.

If not, then try these suggestions:
Try restarting the Service for UiRobotSvc then try to open the file again. If that doesn’t help, try rebooting machine. If that doesn’t help, try reinstalling UiPath. If that doesn’t help, look through some of the forum posts with the same error message.

If all else fails, try technical support

Regards

@HsDev Try this If you have only one xaml file

Create one new project delete the xaml file
Copy the old xaml and paste into the new project folder
