[bug\_fix] AADSTS7000215: Invalid client secret provided. ... The provided client secret is expired

Generate a new client secret in the Azure AD App Registration \(Entra ID\) under Certificates & secrets, immediately copy the displayed secret value \(shown only once\), and update the application's environment variable, configuration store, or secret management system \(e.g., Azure Key Vault, GitHub Secrets, environment files\) with the new secret value. Replace the expired secret.

Journey Context:
Developer has a production service running on Azure App Service that uses a service principal \(App Registration\) to authenticate to Azure Key Vault. Everything works fine for months. Suddenly, on a Monday morning, all requests to Key Vault start failing with "AADSTS7000215". Developer checks the App Service configuration and sees the client secret is still present \(it's hidden in the portal but they have the value in Key Vault... wait\). They check the App Registration in Azure Portal > Certificates & secrets and see that the client secret shows "Expired: Yes" with a red warning icon. They realize that when they created the secret 2 years ago \(or 1 year, depending on policy\), they set an expiration date and never rotated it. The error message explicitly states the secret is expired, not that it's wrong. The fix is to generate a new client secret in the App Registration, copy the new value \(which is only shown once\), and update the application's environment variable or configuration store with the new secret value.
