The 'from' property value in the 'select' action inputs is of type 'String'. The value must be an array.

Posted on by 294

Using a 'Transform data using Power Query' to get and manipulate data from SQL. I then run 'Parse JSON'. That all works, but it appears the data format coming out of the Parse JSON is not what the next step ('Select') requires, as I am getting:

 

The 'from' property value in the 'select' action inputs is of type 'String'. The value must be an array.

 

This is happening in the 'Select' action.

 

The Parse JSON Schema is:

 
  "type""object",
  "properties": {
    "resultType": {
      "type""string"
    },
    "value": {
      "type""array",
      "items": {
        "type""object",
        "properties": {
          "FULLNAME": {
            "type""string"
          },
          "Transaction Date": {
            "type": [
              "string",
              "null"
            ]
          },
          "Client": {
            "type""string"
          },
          "Project": {
            "type""string"
          },
          "Phase": {
            "type""string"
          },
          "Description": {
            "type""string"
          },
          "Hours": {
            "type""number"
          },
          "Amount to Pay": {
            "type""number"
          }
        }
      }
    },
    "evaluationUsage": {}
  }
}
 
The Body of the Parse JSON is:

The Select action returns:

Not sure how to correct. Any help would be greatly appreciated. Thanks!

    What solved this for me was this syntax json(body('HTTP_-_Get_Content_Blob'))  in place of just getting the Body. Note this will vary on what your Http Body Action Name is this one was named "HTTP - Get Content Blob"

    I add this as the answer was not specific enough in my case.

    It looks to me like the error occurs if you hit an item with no comments (null). In that case you have to test for that scenario and do something different if there are no comments.

    Hi @Pstork1 ,

     

    Per @sachk1 response, I'm getting the same error. 

    The 'from' property value in the 'select' action inputs is of type 'Null'. The value must be an array.

     

    I'm trying to retrieve comments with @mentions to display name, comment and date from this article.  Here is my flow.   What step am I missing?

    Re: The 'from' property value in the 'select' action inputs is of type 'String'. The value must be an array.

    Hello @Pstork1 ! maybe you can help me with my code as I suspect it is happening something similar. The message that appears in my case is:

    The 'from' property value in the 'select' action inputs is of type 'Null'. The value must be an array.

     

    And this is my code:

    ACTION 1

    {
        "kind""ApiConnection",
        "splitOn""@triggerBody()['rows']",
        "inputs": {
            "schema": {
                "type""object",
                "properties": {
                    "rows": {
                        "type""array",
                        "items": {
                            "type""object",
                            "properties": {
                                "entity": {
                                    "type""object",
                                    "properties": {
                                        "Power BI values": {
                                            "title""Tabla de Power BI",
                                            "type""array",
                                            "items": {
                                                "type""object",
                                                "properties": {
                                                    "LOGIN": {
                                                        "title""Tabla de Power BI LOGIN",
                                                        "type""string"
                                                    }
                                                },
                                                "required": []
                                            }
                                        }
                                    },

            "parameters": {

        }
    }
     
     
    ACTION 2 (IT IS THE ONE FAILING):
    {
        "inputs": {
            "from""@triggerBody()?['entity']?['Power BI values']",
            "select": {
                "AA""@item()?['LOGIN']"
