Hello,

I have a Cloud flow that run three separate desktop flows in an unattended manner at 3am CST. My flow has been failing, intermittently.

Here are my inputs

{

"host": {

"connectionReferenceName": "shared_uiflow",

"operationId": "RunUIFlow_V2"

"parameters": {

"uiFlowId": "cca68a68-3265-4bff-a170-cc3671c63443",

"runMode": "unattended",

"x-ms-flow-trusted-access": true

}

Here is the output

}

I am running this flow on a 16G of ram, 4 (2.95Ghtz) virtual processors on a virtual machine running Windows Server 2016.

Can anyone help me decipher what the outputs mean or point to as the error?

Cheers!

Peter
