 | **ServiceQuotaExceeded** | Free tier service quota limit reached for Azure AI Search | This error occurs when you attempt to deploy an Azure AI Search service but have already reached the **free tier quota limit** for your subscription. Each Azure subscription is limited to **one free tier Search service**.<br><br>**Example error message:**<br>`ServiceQuotaExceeded: Operation would exceed 'free' tier service quota. You are using 1 out of 1 'free' tier service quota.`<br><br>**Common causes:**<br><ul><li>Already have a free tier Azure AI Search service in the subscription</li><li>Previous deployment created a free tier Search service that wasn't deleted</li><li>Attempting to deploy multiple environments with free tier Search services</li></ul><br>**Resolution:**<br><ul><li>**Option 1: Delete existing free tier Search service:**<br>`az search service list --query "[?sku.name=='free']" -o table`<br>`az search service delete --name <service-name> --resource-group <rg-name> --yes`</li><li>**Option 2: Upgrade to a paid SKU:**<br>Modify your Bicep/ARM template to use `basic`, `standard`, or higher SKU instead of `free`</li><li>**Option 3: Use existing Search service:**<br>Reference the existing free tier Search service in your deployment instead of creating a new one</li><li>**Request quota increase:**<br>Submit a support request with issue type 'Service and subscription limits (quota)' and quota type 'Search' via [Azure Quota Request](https://aka.ms/AddQuotaSubscription)</li></ul><br>**Reference:**<br><ul><li>[Azure AI Search service limits](https://learn.microsoft.com/en-us/azure/search/search-limits-quotas-capacity)</li><li>[Azure AI Search pricing tiers](https://learn.microsoft.com/en-us/azure/search/search-sku-tier)</li></ul> |

 | **MaxNumberOfRegionalEnvironmentsInSubExceeded** | Maximum Container App Environments limit reached for region |This error occurs when you attempt to create more **Azure Container App Environments** than the regional quota limit allows for your subscription. Each Azure region has a specific limit on the number of Container App Environments that can be created per subscription.<br><br>**Common Causes:**<br><ul><li>Deploying to regions with low quota limits (e.g., Sweden Central allows only 1 environment)</li><li>Multiple deployments without cleaning up previous environments</li><li>Exceeding the standard limit of 15 environments in most major regions</li></ul><br>**Resolution:**<br><ul><li>**Delete unused environments** in the target region, OR</li><li>**Deploy to a different region** with available capacity, OR</li><li>**Request quota increase** via [Azure Support](https://go.microsoft.com/fwlink/?linkid=2208872)</li></ul><br>**Reference:**<br><ul><li>[Azure Container Apps quotas](https://learn.microsoft.com/en-us/azure/container-apps/quotas)</li><li>[Azure subscription and service limits](https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits)</li></ul> |
