Unable to process template language expressions in action 'Parse_JSON_2' inputs at line '1' and column '30004': 'Required property 'content' expects a value but got null. Path ''.'.

Hi,

I built a flow to add attachment in MS. Forms to SharePoint. One of the attachments is "not mandatory" and hence might not have attachment some time. In the occasion where no attachment is added, my flow failed. See below for more details:

Dows anyone can share how to tackle this?

Thanks in advance!

You can try adding a condition before the "Parse JSON 2" action to check for the null values, in the yes part of the condition you can leave as it is and in the no part of the condition you can add the "Parse JSON 2" and the next actions after that.

Once you do this change, I don't think you will see any issue with the Parse JSON 2 action.

If the information shared helps you please consider giving a thumbs up 👍 and mark solution as resolved

Thank you for your response.

I followed and still the same error.

Something wrong with the value I used?

Did you find a solution? I have the same problem, checking for a null variable does not solve it.

try to eliminate de "null" function. I let the field empty and it works.

Indeed just check for an empty field.
