Hey Everyone,

we have encountered a weird problem while setting up our new Windows Server Infrastructure with UiPath.

When running workflows attended, everything is working fine.

However, when running unattended everything BUT the verification activities seem to work. These throw the following error:

System.Exception: An internal error occurred during your request! —> UiPath.Testing.Activities.Api.RestHttpRequestException: {‘message’:‘An internal error occurred during your request!’,‘errorCode’:0,‘result’:null,‘targetUrl’:null,‘success’:false,‘error’:{‘code’:0,‘message’:‘An internal error occurred during your request!’,‘details’:null,‘validationErrors’:null},‘unAuthorizedRequest’:false,‘__abp’:true} at UiPath.Testing.Activities.Extensions.HttpResponseMessageExtensions.EnsureSuccessStatusCodeAsync(HttpResponseMessage response)

Does anybody have an idea of what might be going wrong here?

Thanks for your help!

If you can share the screen shot of verify property settings

Also try to add activate window activity before your ui activity add some delay and select wait for page load to complete

The workflow is working fine on another VM in unattended Mode. So I don’t think the settings of the actual activity or the activate function should be an issue.

I also am performing several UI interactions before that so the page load probably also isn’t the issue.

I am out of ideas of what could be the cause of that.

Ok so turns out the only thing needed was to enable View rights for folder packages for the robot account.
