azd deploy fails in version 1.23.1 with "command must be provided if shell is not used"

[fsfc1]

We started seeing azd deploy failures in our GitHub Actions pipeline immediately after the release of azd 1.23.1. We are deploying a .NET Aspire solution to Azure Container Apps. The deployment works perfectly on azd 1.23.0.

Steps to reproduce:

1. Run a GitHub Action workflow using ubuntu-latest.
2. Install the latest azd via: curl -fsSL https://aka.ms/install-azd.sh | bash
3. Run azd deploy --no-prompt.

Expected behavior: Successful Bicep build and deployment.
Actual behavior: The deployment fails during the infrastructure build phase with an internal Go error:

ERROR: failed deploying service '<APP_NAME>': building container app bicep: building bicepparam: failed running bicep build: command must be provided if shell is not used

Environment:
• OS: Linux (GitHub Actions Runner)
• Azd Version: 1.23.1
• Language: .NET 10 / Aspire

Workaround: Pinning the installation to version 1.23.0 resolved the issue: curl -fsSL https://aka.ms/install-azd.sh | bash -s -- --version 1.23.0

@vhvb1989 can you triage this?

[vhvb1989]

@rajeshkamal5050 , this is a regression from #6536
same as: #6593

The tool-creation was changed and there where some places where this was not updated, like this path for Aspire.

I will create a fix

Thanks @vhvb1989 lets fix n create a patch.

Good that users have workaround to use/pin to the previous version

Where are we with this fix? azd deployments still failing as of 2026-02-26 with error: 'ERROR: failed deploying service 'cpdpoc': building container app bicep: building bicepparam: failed running bicep build: command must be provided if shell is not used'. How do I "pin" the version in Azure DevOps Pipeline to get around this until we get a fix?

simply modify your pipeline adding -- --version 1.23.0

  - name: Install azd via package manager
    run: |
      curl -fsSL https://aka.ms/install-azd.sh | bash -s -- --version 1.23.0
    shell: bash

    shell: bash

Or if you're using azd-setup, you can add a version input:

  - task: setup-azd@1
    inputs:
      version: '1.23.0'
    displayName: Install azd v1.23.0 only
