Azure file deletion not working with life cycle management rule

Question

We have a requirement to delete the files after certain days from storage container folders.

I have set a rule to delete them as per below. But looks like this rule is not getting triggered. Please advice.

"rules": [
{
"enabled": true,
"name": "test",
"type": "Lifecycle",
"definition": {
"actions": {
"baseBlob": {
"delete": {
"daysAfterModificationGreaterThan": 1
}
}
},
"filters": {
"blobTypes": [
"blockBlob"
],
"prefixMatch": [
"raw / BV/ landing / BV-data-to-Data-Lake-Integration/events",
"raw / BV/ landing / BV-data-to-Data-Lake-Integration/event_",
"raw / BV/ landing / BV-data-to-Data-Lake-Integration/sensors"
]
}
}
}
]
}````

I tried to reproduce the same in my environment and I got the result successfully:

• If you not getting deleted, make sure the folder or files are already present before creation of the lifecycle management rule.
• The rule applies only to files created after it was created. before if it is present, it will not be deleted.
• Make sure If you are updating or new policy it may takes up to 48Hrs to complete.

Portal:

Code view:

  "rules": [
    {
      "enabled": true,
      "name": "rule1",
      "type": "Lifecycle",
      "definition": {
        "actions": {
          "baseBlob": {
            "delete": {
              "daysAfterModificationGreaterThan": 1
            }
          }
        },
        "filters": {
          "blobTypes": [
            "blockBlob"
          ],
          "prefixMatch": [
            "test/folder1/scores.json",
            "test1/folder1/file.json"
          ]
        }
      }
    }
  ]
}

Also check the any restrictions in place for the container or the blobs like Immutability policies or the blob is leased.
