Flow fails if no attachment

[CiprianPop]

Hi guys,

 I created a flow with around 50 attachments. I created Json for each of the questions. Everything is ok, but if we don't upload an attachment to a question, the flow fails and the rest of the attachments are not uploaded. I used the flow to transfer responses from Forms to a SharePoint List. 

I used the code that was suggested in other posts but with no success. Is anyone able to point me to a possible solution? I would like, if we don't have an attachment to a question to move to the next question.

"content": {
"type": ["number","null"]
}

and

 "content": {},

@CiprianPop  I think we need a little more context on how you are treating this in your flow. Maybe you create a conditional step and check the content with length(..)>0
