Issue with Outlook Get Attachments: ContentBytes structure has changed lately

[CoupalM]

After updating a flow I started to have issues with the results of the Outlook Get Attachment activity (That I did not changed). Before my update, the "ContentBytes" attribute was returning the following object :

{

"$content-type": "application/octet-stream",

"$content": "JVERi0xl......"

}

After the flow update

"JVERi0xl......"

So to fix the issue I had to create the object manually and set the "$content" to the ContentBytes value.

I want to confirm if this is an observed change because if this is true, I'm really worried about using power automate for critical business process if Microsoft perform changes on the results of activities...

Returned value before updating my flow

Returned value after updating my flow (no update on the Get Attachment or Add Attachments activities.)
