Lately, I’ve been experiencing a strange issue: UiPath Studio takes an unusually long time—sometimes up to 30 minutes—to run the Validation Error Checker before I can start debugging or running a workflow.
This started happening suddenly, without any clear change on my side. I have already tried restarting my machine and installing the latest version of UiPath Studio Desktop, but the problem persists.
My projects are not large or complex, and my machine has good standard specs, so I really doubt this is normal behavior. I’ve worked with UiPath for several years, and this slowdown feels completely out of the ordinary.
What steps can I take to either fix this issue or at least identify the root cause?
Check if you have enough CPU and RAM in your Studio machine. If the CPU is almost in 100% usage and if you have less than 8 GB RAM available, expect strange issues/behaviors.
Check with the help of procmon if there are third-party tools (especially monitoring/firewall/anti-virus tools) which are scanning in real-time the Studio process that validates your project. After finding them, work internally to create custom rules to not touch the UiPath processes and dll files.
Are you working across a network or VPN? You should always copy projects to a local folder to work on them. And don’t use a local folder that is connected to OneDrive or a similar cloud sync system.
I’d argue this is good for any work, but especially coding work.
OneDrive connected directly to a folder causes never ending issues and is always the first thing I nuke on a work laptop when I get a new one.
Hello @postwick
Well right now I’m not working across a network or a VPN and niether with a folder connected to OneDrive. So that can be discarded.
Yet I find the OneDrive issue interesting, later on I’m going to be working with excel files that will be synced with the OneDrive Cloud, could I be expecting problems from it?
My RAM seems fine and I dont have any third party tools interrupting.
As an insight I constantly get the pop up notification in my studio while executing a project as well as during developing without executing or debugging it suddenly pops up. Any insight of what this could mean?
I’m not sure about how reading Excel files from a OneDrive folder will go. I’ve just had issues with UiPath project files in a OneDrive folder, the sync process seems to interfere with UiPath.
In my opinion yes. The One Drive service on your desktop is trash in my experience.
What can often happen is you update one or more files at the end of a process, but the process finishes before the slow ass one drive thing syncs, and then you simply lose the changes.
I would never accept it in an enterprise solution, instead I would work directly with the file on Sharepoint via the integration service to avoid the ‘One drive assistant’ middle ware which goes wrong.
Well the actions that have to be taken by the robot in the excel file are a little more complex than what the activities available in studio are able to do with integration service and I dont know how plausible would be to do something like download the excel file, edit it, and then upload it again to the cloud.
