Logic Appp trigger for Azure Blob Storeage is not working

Good afternoon everyone,

I’m trying to create a simple Logic App, but for some reason that I can’t understand, I am unable to save it. The Logic App is straightforward, it should only post a message on Slack when an Azure Blob Storage trigger is executed. However, there is something wrong, and it won’t let me save the application.

Here’s the code:

{
  "definition": {
"$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
"actions": {
  "Publicar_mensaje_(v2)": {
    "type": "ApiConnection",
    "inputs": {
      "host": {
        "connection": {
          "referenceName": "slack"
        }
      },
      "method": "post",
      "body": {
        "channel": "C04MV4K08TW",
        "text": "Test from Azure Logic App :::{hidden}:::"
      },
      "path": "/v2/chat.postMessage"
    },
    "runAfter": {},
    "trackedProperties": {}
  }
},
"contentVersion": "1.0.0.0",
"outputs": {},
"triggers": {
  "When_a_blob_is_added_or_updated": {
    "type": "ServiceProvider",
    "inputs": {
      "parameters": {
        "path": "configurationscontainer/configurations_mock.json"
      },
      "serviceProviderConfiguration": {
        "connectionName": "AzureBlob-2",
        "operationId": "whenABlobIsAddedOrModified",
        "serviceProviderId": "/serviceProviders/AzureBlob"
      }
    },
    "conditions": [],
    "trackedProperties": {
      "key": "connectionvalue"
    }
  }
}
 },
"connectionReferences": {
"AzureBlob-2": {
  "api": {
    "id": "/serviceProviders/AzureBlob"
  },
  "connection": {
    "id": "/serviceProviders/AzureBlob/connections/AzureBlob-2"
  },
  "connectionName": "AzureBlob-2",
  "authentication": {
    "type": "ManagedServiceIdentity"
  }
},
"slack": {
  "api": {
    "id": "/subscriptions/{hidden_id}/providers/Microsoft.Web/locations/westeurope/managedApis/slack"
  },
  "connection": {
    "id": "/subscriptions/{hidden_id}/resourceGroups/{hidden}/providers/Microsoft.Web/connections/slack"
  },
  "connectionName": "slack",
  "authentication": {
    "type": "ManagedServiceIdentity"
  }
}
},
"parameters": {}
}

Here’s an image from the error (I can’t copy the text):

I would really appreciate any possible help, it’s the first Logic App I’m developing and I’m starting to feel quite desperate. 🙁

PD. Before asking I obviously did a lot of research but…no such luck.

Thanks in advance to everybody.

    Try to follow above design or code and you will get output as I have got and if still no success, I would suggest you to raise a support request.
