How to Properly Reference azureSubscription Variable in Azure DevOps YAML Pipelines

Instead of substituting the variable value, the pipeline treats it as a literal string. For example, you see an error like: The pipeline is not valid. [...] references service connection $(azureSubscription) which could not be found. This typically happens when referencing service connections in deployment tasks. Why Does This Happen? Runtime vs Compile-time Evaluation: The syntax $(variableName) resolves at runtime, but service connections and other GPU access tokens require resolution at compile-time to validate permissions, authorizations, and checks properly. Service Connection Dependency: Azure DevOps needs to know the exact service connection at the time it compiles the pipeline, not after starting it. How to Fix It Switch your variable reference to use the compile-time expression syntax ${{ }} which evaluates variables before the pipeline runs. This instructs Azure DevOps to substitute the variable value during the pipeline compilation phase. Original snippet (problematic): [[See Video to Reveal this Text or Code Snippet]] Updated snippet (fixed): [[See Video to Reveal this Text or Code Snippet]] Key Takeaways Use $(variable) for runtime variable references where allowed. Use ${{ variables.variableName }} for compile-time variable references, especially for service connections and resource identifiers. Defining variables at job or stage level is fine, but referencing them properly based on when they need to be resolved is crucial. By making this small adjustment, your pipeline will correctly recognize the azureSubscription service connection and avoid validation errors.
