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!

{ "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" ] } }

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.

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.

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!

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

Hello, 

I did as you told and my flow is still not getting this condition.

This is how I done it:

And this is the result:

Do you have an idea what might be the case here?

Been trying to search it but with no success

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?

[Anonymous]

@5013, in my case problem was silly- instead of using "length" i did use "lenght".

Hello,

I was having the exact same error mentioned here, although I was trying to parse the HTTP action output, error says that it is getting null for the content in Parse JSON action, since I found that I am getting the value in my http action then why it is null in parse json action.

The thing I tried is, I inserted value of body as expression in content field of parse action instead of inserting it as dynamic content and it worked.

Thanks,

Any help to solve this flow?  @v-bacao-msft

[powerNOTomate]

How can I make the flow skip on the Parse Json sections if a user has not uploaded, I have multiple upload sections, I cant seem to allow the flow to progress if one of the upload sections is not completed.

[Stella_Sun]

If no, how are you handling the nulls then? I am trying to make my automation work. Can I message you in email to figure out? thanks so much.
