Re: Parse JSON Error

Hi!

It sounds like one of the answers was left empty so the property does not exist (null).

Can you share a screenshot from your Parse JSON input, and also from the JSON sintax you currently chose?

Thanx!

Re: Parse JSON Error

Hello @EmployeeA

Can you try this:

{ "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": {} }} }

If the above does not work. Please add a Compose action before the Parse Json action.
In the Compose put the dynamic content you are referencing in the parse JSON.
This is just to see what the JSON output looks like from the run.

Re: Parse JSON Error

Hi @EmployeeA ,

There are two ways to solve this issue.

The first one is set the file upload required.

Another method is to use length() function to check if the user has uploaded the file.

Hope this helps.

Best Regards,

Re: Parse JSON Error

Hi Guys,

I am new to this automation and trying to figure out ways to attaching a uploaded file on forms to sharepoint item as an attachment.
-filled out a form
-uploaded two docx files
-found out you need to use get file content for onedrive business to attach files to the sharepoint list/item
-found out you have to parse forms upload into json to get id for onedrive file content id
-I have visited all recent blogs and posts copying and pasting a known-working schema
-confirmed file already uploaded via forms
-fails with same error message :

InvalidTemplate. Unable to process template language expressions in action 'Parse_JSON' inputs at line '1' and column '2856': 'Required property 'content' expects a value but got null. Path ''.'.

Please advise

Hi!

My humble suggestion is to open a new topic. Superusers tend to pay more attention to unanswered topics, and this one already ave been marked as solved

Thanx!

Re: Parse JSON Error

As far as why this is happening, the output from your flow isn't returning a result, check the call that you're making to the API/entity.
As far as the error definition, it clearly tells you that the output is empty/null, and therefore parse json cannot parse a null value. Never parse json without checking for a null value. In order to avoid this error, you have to check if the body value is null, and then parse JSON. (However you can avoid checking for null, if you know for sure that your output will always yield a json result)

Check if the returned json is null

Re: Parse JSON Error

Hi TomasBan, it is also not working for me. I tried all the proposed solutions and even included "null" to every JSON property but without success in getting rid of the JSON error. Did you maybe found a solution?
