Problem when I try to run UI Flow

I created a UI flow using desktop app.

2020-09-26_11h18_59.png

When I run the flow from editor It's ok.

2020-09-26_11h19_24.png

It's a simple flow just to show a message.

When I close editor and try to run from the list i get the following message

Hi @Sokg 

 

We were able to reproduce the issue by adding an invalid character like ' in the folder path of the WAWorkspace folder.

 

Please open the file %LocalAppData%\Microsoft\PowerAutomate\config.json and check if there are any invalid parameters in the workspaceDirectory.

 

Also note that we are currently working towards a fix.

 

I hope the above helps!

That's strange! I just tried the same steps and it worked for me (see below). I would check if you have pop-up enabled. I am sure you have tried logging off and logging back in also PAD being in preview and its been couple of days since you posed the question may be a fix has been applied. Just give it try and let us know if you continue to experience issues.

 

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Thanks

Hi @Sokg 

 

You could try the following steps:

 

1. Uninstall PAD from your machine (the app is installed as "UI flows")

2. Delete the following folders 

  1. C:\Users\YourUserName\AppData\Local\Microsoft\PAD.Console.Host.exe_StrongName_*
  2. C:\Users\YourUserName\AppData\Local\Microsoft\PAD.Designer.Host.exe_StrongName_*
  3. C:\Users\YourUserName\AppData\Local\Microsoft\PowerAutomate
  4. C:\Users\YourUserName\AppData\Local\Microsoft\PowerAutomate.Desktop

3. Install PAD again 

 

Please check if the above resolves the issue.

 

I hope it will be helpful!

 

Hi @PetrosF-MSFT

Thanks

Hi @Sokg 

 

Let's try one more solution:

 

Please open the file "%LocalAppData%\Microsoft\PowerAutomate\config.json" and make sure that it points to a local directory. The default location should be "%UserProfile%\Documents\WAWorkspace".

 

Then, please delete all the folders inside "%UserProfile%\Documents\WAWorkspace" and check if the issue persists.

 

Thank you!

Hi @PetrosF-MSFT 

 

I deleted the folders, but problem still here.

 

I deleted all UI flows, I had created, and create a new one, but same message pop up again.

 

 

Any ideas???

Hi @Sokg 

 

Could you let me know what is the exact version that you are using so that I could forward this to our developers?

My version is:
