[Fixed] The property ‘content’ must be of type JSON in the ‘ParseJson’ action inputs, but was of type ‘application/x-www-form-urlencoded’

I got this error when I tried to Parse JSON when a request is received in Power Automate. I tried many ways to Parse the data but could not succeed. Finally, I got a lead by just randomly doing the try and error method.

To explain the scenario, I was creating a WhatsApp bot using Twilio and Power Automate. Whenever any new message is received, Twilio sends a JSON payload to Power Automate. That payload contains many properties such as from, to, message, etc.

Initially, I tried the action Parse JSON. I got the below error.

BadRequest. The property 'content' must be of type JSON in the 'ParseJson' action inputs, but was of type 'application/x-www-form-urlencoded'.

The reason for the above error is because the content-type is not application/json.

Fix

We will not parse this request. Instead, we will convert all the values [$formdata] to string and then split them by a delimiter that will create an array. In my case, the delimiter is “&”.

Compose 2 contains the below expression –

string(triggerBody())

Initialize variable contains the value as Output from Compose 2. Compose 3 contains the below expression.

split(variables('whatsAppBody'),'&')

That’s it. Now, you have an array with all the $formdata key value pairs. Go ahead and iterate through each element using Apply to Each.
