title: I am getting a vmSize error when trying to deploy a batch service pool using bicep
body: <p>I have the following Bicep code:</p>
  <pre><code>resource pool 'Microsoft.Batch/batchAccounts/pools@2021-06-01' = {
    name: '${bs.name}/run-python'
    properties: {
      scaleSettings: {
        fixedScale: {
          nodeDeallocationOption: 'TaskCompletion'
          targetDedicatedNodes: 1
        }
      }
      deploymentConfiguration: {
        cloudServiceConfiguration: {
          osFamily: '6'
        }
      }
      vmSize: 'standard_A1_v2'
      startTask: {
        commandLine: 'cmd /c &quot;pip install azure-storage-blob pandas&quot;'
        userIdentity: {
          autoUser: {
            elevationLevel: 'NonAdmin'
            scope: 'Pool'
          }
        }
        waitForSuccess: true
      }
    }
    dependsOn: [
      bs
    ]
  }
  </code></pre>
  <p>Where I try to create a pool for my batch service, but when I try to deploy it, I get the following error:</p>
  <p><code>{&quot;code&quot;:&quot;DeploymentFailed&quot;,&quot;message&quot;:&quot;At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.&quot;,&quot;details&quot;:[{&quot;code&quot;:&quot;PropertyName&quot;,&quot;message&quot;:&quot;vmSize&quot;}]} </code></p>
  <p>So I think the problem is the vmSize, but there I cannot find concrete example on what the value should be.</p>
