Pulumi extension task fails when ran as part of a deployment

[tap1992]

Describe the bug

Using the Pulumi Azure DevOps extension's task within a deployment job it fails with the below error. If i copy and paste the same task into a normal job it works perfectly fine.

##[error]Error: There was an error when attempting to execute the process '/__w/_temp/c0162cb7-b00c-44f7-a09c-82bb8eefcc6a/pulumi/pulumi'. This may indicate the process failed to start. Error: spawn /__w/_temp/c0162cb7-b00c-44f7-a09c-82bb8eefcc6a/pulumi/pulumi ENOENT

To Reproduce

Using YAML pipelines, use a normal job with steps and utilise the pulumi task as shown below:
jobs:

• job: test
  steps:
  • task: Pulumi@1
    inputs:
    azureSubscription: ***
    command: 'preview'
    cwd: ''
    stack: ''
    args: '--diff'
    loginArgs: azblob://***

It should work as normal.
If we use the deployment version of a job as per below it will fail:

• deployment: deploy_job
  environment: ***
  workspace:
  clean: all
  strategy:
  runOnce:
  deploy:
  steps:
  - task: Pulumi@1
  inputs:
  azureSubscription: ***
  command: 'preview'
  cwd: ''
  stack: ''
  args: '--diff'
  loginArgs: azblob://***

Expected behavior

Pulumi preview should run and generate the output in logs.

It seems that you will need to include a step to checkout the source code in your deployment job since they do not automatically clone the source repo. See https://docs.microsoft.com/en-us/azure/devops/pipelines/process/deployment-jobs?view=azure-devops.

A deployment job doesn't automatically clone the source repo. You can checkout the source repo within your job with checkout: self. Deployment jobs only support one checkout step.

deploy:
  steps:
    # Add this step before running Pulumi.
    - checkout: self

    - task: Pulumi@1
      inputs:
        azureSubscription: ***
        command: 'preview'
        cwd: ''
        stack: ''
        args: '--diff'
        loginArgs: azblob://***

@tap1992 are you still encountering a problem using the task extension?

Thanks All - Adding the "- checkout: self" fixed it!
