I am passing attachment information from PowerApp to Power Automate. In Power Automate I am calling Invoke HTTP action method to call ServiceNow REST api to add attachment. This method is attaching attachment but when i download from ServiceNow it is in corrupted mode. I tried same content bytes to create file in one drive and it worked perfectly. What could be the possible reason for document corruption. After investigation i found that, final document and original document sizes are different. If original document size is 200KB, final document size is coming as 300KB.

When I use HTTP action then it is working fine, but when I use Invoke HTTP request then not working as expected. See below screenshots for reference.

Off hand, and not being familiar with the ServiceNow REST API, the only thing I can think of is are you sure you are properly encoding the file when you are calling the HTTP rest API? Many APIs only support file attachments being encoded in a certain format (i.e. binary, base64, etc).
