Hi,

I am trying to create a flow that will be triggered when a MS Forms will be filled to do the following:

1. Populate the inputs in a MS Doc file (working fine).

2. Save the attachment from MS Forms to a folder in Sharepoint (having error).

Following is what I did for step # 2 and it seems to be not working. Any help would be greatly appreciated :)

There are probably other ways to do this, but the first thing I do is parse the JSON of the attachment question in order to get the name:

You can use the following for the scheme since it should be consistent in MS Forms:

{

    "type": "array",

    "items": {

        "type": "object",

        "properties": {

            "name": {

                "type": "string"

            },

            "link": {

                "type": "string"

            },

            "id": {

                "type": "string"

            },

            "type": {},

            "size": {

                "type": "integer"

            },

            "referenceId": {

                "type": "string"

            },

            "driveId": {

                "type": "string"

            },

            "status": {

                "type": "integer"

            },

            "uploadSessionUrl": {}

        },

        "required": [

            "name",

            "link",

            "id",

            "type",

            "size",

            "referenceId",

            "driveId",

            "status",

            "uploadSessionUrl"

        ]

    }

}

You then use the Body from the Parse JSON action in the apply to each

I use a condition to check that the file size is greater than 0 as I have had instances where a 0-byte file gets attached and then the flow fails

For the get file content action, use the id from the Parse JSON action

Then in the create file action, use the name from the Parse JSON action

Some minor adjustments may be needed as it appears your MS Forms form is saved in SharePoint. All of mine are in OneDrive.

Please show a screen shot of the trigger.

Is this a personal MS Form (where the responses are stored in your OneDrive, or is it a Group form (where the responses are stored in a SharePoint site)?
