Hi @Andrew_Spence ,

Few questions to understand a bit better the situation:

  • Does it start and at some point it crashes with the message above? or is it complaining and preventing you from even starting?
  • Did you try to Debug instead of Run? If so, can you send a screenshot of the activity that fails? (if its not the case mentioned above preventing you to start)

Thanks!

It’s starting and straight away it is opening then closing then showing the error message.
Can I attach my files here. I’m not sure how.

I’ve run the project in debug mode and got stuck on the following. I can see that the arguments showing are not the same as in my project. How can this be?

As the error message indicates, somewhere you’re using a dictionary and the key you’ve specified doesn’t exist. Post a screenshot of the arguments you see when you click the Import Arguments button.

in_Config is a dictionary. Confirm that both of those keys (ACMEApplicationPath and ACMECredentials) exist in the dictionary, which is read from an Excel file so check the Excel file to make sure you have those in there. Spelling is exact.

Also, I can tell by the error message that you’re on old versions of things. Newer versions tell you which key is missing.

What version of Studio and UiPath.System.Activities are you on?

10

I’m using an enterprise version of Studio 2021.10.5 and 2021.10.4 for UiPath.System.Activities. I can’t upgrade it sadly.

I had missed the _ in the ACME path. I’m using credential manager. Now I’m getting this error.

12

The error message is pretty clear, it didn’t find an Asset with that name. You said you’re using credential manager - that’s a Windows thing and is different from an Asset (which would be in Orchestrator).

13

I’m not using orchestrator so i’m not sure why it is saying that?

14

Because you used the Get Credential activity which pulls the username and password from a credentials Asset in Orchestrator.

If you want to use credential manager, that’s the Get Secure Credential activity.
