Uipath failing to install workflows due to missing packages... that don't exist

hello all!

Starting last week we’ve had two different developers encounter an issue where they:
-Built an automation on their dev machine without issue.
-Published to Orchestrator without issue.
-Went to install it on a test machine and the install failed
-The error that generated for the most recent one was:
"UiPath.Corelpc.RemoteException: NU1102: Unable to find package UiPath.Mail.Activities with version (=1.23.0)

The funny thing is, v1.22.2 just dropped in March and there IS no 1.23 that I can find, even on a prerelease channel. When we checked the code the Package manager was showing the right version but when I opened up the project.json file it also reflected 1.23.

We were able to delete the project.json file and let studio recreate it. We had to add in a few missing packages that were NOT detected but we did have a short term fix.

The other error was an entirely different package with a version number that also did not exist.

Has anyone come across this before? We’re concerned that this just started occurring and has happened twice in the last 10 days. Any help or thoughts would be greatly appreciated.

Cheers!

You probably could have just edited the version in the existing project.json instead of going through all that hassle deleting the file etc.

By the way, it doesn’t detect and add packages. When it recreates project.json it just uses the default packages that you’d get if you created a new blank project.
