I'm on 01-azure-search exercise, specifically "Use the REST API to update the search solution" step located at this url:
https://microsoftlearning.github.io/mslearn-knowledge-mining/Instructions/Exercises/01-azure-search.html

I'm getting below output specifically "OperationNotAllowed"

"PS E:\Projects\mslearn-knowledge-mining\Labfiles\01-azure-search\modify-search> .\modify-search.cmd

Arthur Zaslawski,

Like Vasim mentioned in their response, you can get the quota and usage first.

To get the Azure Cognitive Search quota and usage, you can follow these steps:

Navigate to your Azure Cognitive Search service in the Azure portal

Click on "Usage + quotas" in the left-hand menu.

Here you can see the current usage and quota for your service, including the number of documents indexed, the number of indexers running, and the number of queries made.

Next if you want to see how many queries you have made in the current month, you can use the Azure Monitor service.

Navigate to your Azure Cognitive Search service in the Azure portal.

Click on "Monitoring" in the left-hand menu.

Click on "Metrics" in the top menu.

Select your search service and the "Search" category.

Select the "Search Requests" metric.

Set the time range to the current month.

You can now see the number of search requests made in the current month.

Check these Azure Cognitive Search documentation for more details:

Monitor Azure Cognitive Search with Azure Monitor

Azure Cognitive Search usage and quotas

The 403 Forbidden error when creating an Azure Cognitive Search index with REST APIs is likely due to an incorrect or missing admin API key. Make sure that you have provided the correct admin API key in Postman, as well as the other required variables such as the search service name, index name, connection string to your Azure Storage account, and container name. Double-check that you have followed the instructions in the tutorial Tutorial: Use REST and AI to generate searchable content from Azure blobs correctly, and that you have created a search service and obtained the necessary information such as the service URL and admin key.

---References:

Tutorial: Use REST and AI to generate searchable content from Azure blobs

Quickstart: Create an Azure Cognitive Search index using REST APIs

I hope this helps! Let me know if you have any further questions.

Hi Arthur Zaslawski,

Thank you for reaching out to Microsoft Q&A forum.

The "OperationNotAllowed" error message signals an attempt to alter a field that's immutable. Specifically, the error points out an effort to modify the existing field named metadata_storage_name, which is not allowed.

Within Azure Cognitive Search, some fields are designated as system-managed and are handled exclusively by the system. metadata_storage_name falls into this category, and ordinarily, it's advised not to endeavor to change it.

To address this problem:

1.Check your modification script file to ensure that you're not trying to alter the metadata_storage_name, field.

2.If adjustments to other fields are necessary, ensure they comply with the guidelines outlined by Azure Cognitive Search.

After rectifying the script, attempt the modification again to update your Azure AI Search solution.

Please review the provided document for guidance before creating an Azure AI Search service: https://learn.microsoft.com/en-us/azure/search/search-create-service-portal

Please check this issue as another customer has encountered the same problem, but it has been resolved: https://github.com/MicrosoftLearning/AI-102-AIEngineer/issues/62

If the issue continues, please let us know, and we'll gladly provide additional assistance.

If the solution provided has helped resolve the problem, please consider giving it a "thumbs up".

Thank you.

SiddeshTN, Yes I agree with you. It appears that some of the fields are immutable thus the error message. Even though the MS Learn instructions specified to alter these fields. I have moved on with the exercise and completed it w/o altering this particular field. I appreciate your quick response and very supportive approach. The links you have provided are very helpful as they allow me to better understand how Azure AI Search works. Thank you

Update index.json and change that section as follows:

{

"name": "metadata_storage_name",

"type": "Edm.String",

"facetable": false,

"filterable": true,

"key": false,

"retrievable": true,

"searchable": false,

"sortable": true,

"indexAnalyzer": null,

"searchAnalyzer": null,

"synonymMaps": [],

"fields": []

},
