Hi all, I'm starting to use Pulumi as a pilot for our infrastructure. Would love some help with an issue please. It maybe a common rookie error. All good using the CLI and now creating an Azure Pipeline. Using the Pulumi@1 task There are 3 jobs. 1. Pulumi Preview ✅ 2. Manual Intervention ✅ 3. Pulumi Up ❌ The 1 and 2 work fine. The 'pulumi up', but it fails with...

##[debug]   stack
##[debug]   select
##[debug]   myorganisation/bg/dev
/home/vsts/work/_temp/01d522e5-8d36-46cb-863b-4387991ea26a/pulumi/pulumi stack select myorganisation/bg/dev
##[debug]task result: Failed
##[error]Error: There was an error when attempting to execute the process '/home/vsts/work/_temp/01d522e5-8d36-46cb-863b-4387991ea26a/pulumi/pulumi'. This may indicate the process failed to start. Error: spawn /home/vsts/work/_temp/01d522e5-8d36-46cb-863b-4387991ea26a/pulumi/pulumi ENOENT

It looks like it fails on the 'select stack', but this is fine in the preview and is identical. The YAML looks like
