Null Value Error in Parse JSON

Hello I receive the following error when running my flow.

Unable to process template language expressions in action 'Parse_JSON' inputs at line '1' and column '33823': 'Required property 'content' expects a value but got null. Path ''.'.

Below is my Parse JSON schema:

{

"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"

]

}

The flow is pulling picture attachments from a Microsoft Form and putting it into a sharepoint grid. I want it to allow a null value, but I'm not entirely sure how. There are multiple attachments from different forms questions. I am still fairly new to this, so any help would be appreciated. Thank you!

Null Value Error in Parse JSON

Hey!
Try to modify your array like this:

{

    "type": "array",

    "items": {

        "type": "object",

        "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": {}

        }

    }

}

Every time you need to pass values that may be empty, you need to add the "null" type in the parse and remove the required part.

Hope it helped!

Re: Null Value Error in Parse JSON

Put a condition before the Parse JSON action and test the input to see if its blank. only execute the Parse JSON step if the input isn't blank.

Re: Null Value Error in Parse JSON

Thanks Pstork1,
Would you be able to elaborate a bit more on how to bypass the parse JSON if it is null?

Re: Null Value Error in Parse JSON

The problem is that the value you are trying to Parse is null. You need to put a condition in to evaluate the value before you feed it to the Parse JSON. If the value is empty (null) then you need to bypass the parse JSON or use a Parse JSON that is using static content.
