Hi @bpwwer ,

After I updated IoX to 6.2.1 Vue will not start correctly. The error is below. I deleted the plugin and reinstalled it, but the error remains.

Update:

I just saw another thread regarding the Boto3 file. I had to reflash my eisy prior to doing the upgrade. I just installed the dev packages from the AC but the error is still there.

Thanks for any advice.

It's working fine on my eisy, but I'm on the staging branch so have more updates on mine than on the production or beta branches.

I do see in release notes that UDI has been adding python packages so it may be that the current production branch doesn't have that package yet.

Thanks Bob,

I actually have 2 eisy's running and I compared the configurations of the machines. See attached. The Pelham machine has the Vue that will not run. It runs fine on the Clermont machine. I queried the Clermont machine (works)and couldn't find any indication that boto3 is installed or running.
