How to add several attachment for approval (various file type)

I've tried to create approval with attachment by manually trigger a flow with input file content more than 1 file (I added 2 file content for input) then try testing. it fail many times for property as show 

"InvalidTemplate. Unable to process template language expressions in action 'Start_and_wait_for_an_Pre-approval' inputs at line '1' and column '2837': 'The template language expression 'triggerBody()['file_1']['contentBytes']' cannot be evaluated because property 'file_1' doesn't exist, available properties are 'text, date, text_1, number, email, email_1, file, text_2, email_2'. Please see https://aka.ms/logicexpressions for usage details.'."

Hello @PamelaReeve27 

The output from your trigger includes references to your files. The ID of File_1 is file, the ID of File_2 is file_1 - yes confusing 🙂

I made a small test and came up with this! Output from the trigger with two files defined as input - File_1 and File_2 - gives:

 

{
  "type""object",
  "properties": {
    "file": {
      "title""File_1",
      "type""object",
      "x-ms-dynamically-added"true,
      "description""Please select file or image",
      "x-ms-content-hint""FILE",
      "properties": {
        "name": {
          "type""string"
        },
        "contentBytes": {
          "type""string",
          "format""byte"
        }
      }
    },
    "file_1": {
      "title""FIle_2",
      "type""object",
      "x-ms-dynamically-added"true,
      "description""Please select file or image",
      "x-ms-content-hint""FILE",
      "properties": {
        "name": {
          "type""string"
        },
        "contentBytes": {
          "type""string",
          "format""byte"
        }
      }
    }
  },
  "required": []
}
Observe how the objects are named - "file" = "File_1" and "file_1" = "File_2" - the name you gave are only the display names 🙂
Hope this helps you on the way. Kind regards, John

Hi @JohnAageAnderse 

  Thank you. OK, it's about file name not match. Previously I thought it missing properties so I tried to add properties but don't know how to. 

  However I delete action of add input file and re-do then define file name as you mentioned. It's work! thank you very much. Be safe and be healthy, Pamela
