@Hassan Kaleem Thanks for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this

I am checking with internally on this and will update you here once I hear back from them.

Meanwhile can you confirm are you trying to create an indexer from the azure files or are you trying to create any other indexer? If azure files, please note that current this is in public preview and creating the indexer is not possible through portal.

But the above image that you shared is related to indexer configuration from portal I am unsure how you are configuring this.

I have added this variable in the skillset and in Indexer as well, Still i am getting Null AttachmentCount.
SkillSet

{
      "@odata.type": "#Microsoft.Skills.Util.ShaperSkill",
      "name": "AttachmentCountShaper",
      "description": "Count attachments",
      "context": "/document/metadata",
      "inputs": [
        {
          "name": "attachments",
          "source": "/document/metadata/attachments"
        }
      ],
      "outputs": [
        {
          "name": "output",
          "targetName": "attachmentCount"
        }
      ]
    }

Indexer

{
      "sourceFieldName": "/document/metadata/attachmentCount",
      "targetFieldName": "attachmentCount"
    }

I have to count the attachments in the eml file, first i added a column in the indexes, then updated the skillset to count the attachment @odata.type": "#Microsoft.Skills.Util.ShaperSkill, finally i added that in the indexer, But still the attachment count is null.

@Hassan Kaleem I have checked with internal team on your ask, currently there is no way to currently count attachments. Based on the details and screenshot that you have shared the functionality you are using is not supported.

You can find the skillset language and what is possible here: Skill context and input annotation reference language - Azure AI Search | Microsoft Learn

However, you can add your own logic through a custom skill (Custom Web API skill in skillsets - Azure AI Search | Microsoft Learn, with the definition similar to the below, but add the logic to the function app

{ "@odata.type": "#Microsoft.Skills.Custom.WebApiSkill", "description": "A custom skill that counts the number of attachments in a blob", "uri": "https://my-custom-skill.azurewebsites.net/api/CountAttachments", "httpMethod": "POST", "timeout": "PT30S", "batchSize": 1, "context": "/document", "inputs": [ { "name": "blob", "source": "/document" } ], "outputs": [ { "name": "attachmentCount", "targetName": "attachmentCount" } ] } ],

@Hassan Kaleem Thanks for response and apologize for the delay in my response.

As suggested earlier have you create custom skillset and you are trying to count the attachments?
