Hi,
I've seen a few responses to how to update the Parse JSon code to get Flow to bypass it if the field is left blank, but I've not seen anything that explained explicitly where they update code goes.
In my case, I'm trying to bypass an attachment upload field. If anyone could help me bypass Parse JSON when the field "Attach Terms" is left blank I will be very grateful.
the Schema is as follows:
@eliotcole , @SPOLHE-C thank you for this. I've updated the schema and the flow now works.
Really appreciate the support.
Honestly no bigs! I hadn't realised you had also posted, so I just swerved around you a bit ;-). Frankly I was just thankful that you had, as it meant I could type it all up a bit quicker! 😅
Also, @GMorley , if you want the whole thing to carry on if the input is nil, then you can use a 'Run after' on the following flow action to ensure that it runs whether or not the JSON parser does its thing. Just make sure that your following actions are capable of dealing with a lack of information there. 😉
However, I think deeper interactions would require a bit more of your flow up here.
Hi, @GMorley , if I've understood you correctly, the code goes in the Schema. You essentially tell the Schema that it's OK to set a blank value, and not fail the input.
I'll dig it out, but I may have mentioned it on here at some point, too.
Ah, basically what @SPOLHE-C said ... except the array bracket goes teh other side of the field name.
So, I couldn't see AttachTerms in your schema, so I've used "id" as the field that might be without data, I would set that up in the schema like so:

"items": {

"properties": {

"type": "string"
},
"link": {
"type": "string"

"id": {

"required": [
"name",
"link",
"id",
"type",
"size",
"referenceId",
"driveId",
"status",
"uploadSessionUrl"
]
}
}
If you're happy with the flow otherwise, you can adjust the JSON directly to accept a null. In your code sample, where it says "type": "string", change that to
"type": ["string","null"]
(do the same with "type": "integer" but NOT "type": "array").
...I'll look forward to a more elegant solution in the replies. (Edited to fix a typo.)
I've had a go but I don't really understand what I'm trying to acheive with the filter.
I thought it was a case of checking the form response for attachements and if it does not contain blank then proceed with the Parse.
But if it doesn't do the Parse because the field was blank, it also wont proceed to send the emails. I want it to send the emails whether or not there is an attachment. I just don't want the flow to fail because a file wasn't attached.
I suppose i could put the emails parallel to the Parse JSON so that the attachments don't effect the emails but the flow will still fail at Parse JSON.
Hi, Thanks for responding,
Since it's the Parse that's failing, I assume I need to filter before the Parse, not before the Apply to each? The flow isn't getting as far as apply to each.
I'm assuming From should be the Form response ID, and name is the Attach Terms field?
I know I'm asking you to spell it out for me, but this is my first time exploring what flow can do. Thank you for your help.
Hi @GMorley
You can use the filter array action (where the field is not empty) and then run your apply to each on this filtered array.
As the filtered array does not contain your blank attachment key, it would not be in the array.
