Hi,

The root cause here is converting your content bytes dynamic content into a form submission. Here's an example:

{
"$content-type": "multipart/form-data",
"$multipart": [
{
"headers": {
"Content-Disposition": "form-data; name=\"file\"; filename=\"example.pdf\""
},
"body": "@{base64ToBinary(outputs('Get_file_content')?['body']?['$content'])}"
},
{
"headers": {
"Content-Disposition": "form-data; name=\"additionalParameter\""
},
"body": "parameterValue"
}
]
}

It seems like every webservice is slightly different in regards to the headers and exact format but I would start with just adding the expression base64ToBinary() and see if that solves it; otherwise you will need to figure out what the requirements are for the web service you are posting to and modify the body of your http request to something similar to the above. I just went through this exercise with one of my flows.
