I have a flow that does a couple of things

1) Gets attachments from the form

2) Creates using HTML a pdf showing the information from the form

3) gets the PDF and the form attachments then put them in an email

 

issue

To get the attachments from the form I am using a parse JSon

{
    "type": [
        "array",
        "null"
    ],
    "items": {
        "type": [
            "object",
            "null"
        ],
        "properties": {
            "name": {
                "type": [
                    "string",
                    "null"
                ]
            },
            "link": {
                "type": [
                    "string",
                    "null"
                ]
            },
            "id": {
                "type": [
                    "string",
                    "null"
                ]
            },
            "type": {},
            "size": {
                "type": [
                    "integer",
                    "null"
                ]
            },
            "referenceId": {
                "type": [
                    "string",
                    "null"
                ]
            },
            "driveId": {
                "type": [
                    "string",
                    "null"
                ]
            },
            "status": {
                "type": [
                    "integer",
                    "null"
                ]
            },
            "uploadSessionUrl": {}
        },
        "required": [
            "name",
            "link",
            "id",
            "type",
            "size",
            "referenceId",
            "driveId",
            "status",
            "uploadSessionUrl"
        ]
    }
}
 
Even with the above "Null" my flow is failing when a use is NOT uploading a file, how can I make PA ignore this step and move on when no files are uploaded through the form?
 
Thank you

    Hi @Helloworld2 ,

     

    You can use an Condition to test whether a file was uploaded. If the file upload question field is not empty then a file was uploaded and we can continue with the rest of the flow, for example:

     

    snag_39d757b.png

     

    If the file upload field is not empty then a file was uploaded and continue with the rest of the flow in the Yes block or take some other actions in the No block:

     

    snag_3ac8deb.png
