File upload from custom HttpApi plugin

[Piotr Gabryś]

Hi, I am developing my first HttpApi plugin and struggling with file upload. I am getting an error:

ansible/module_utils/connection.py", line 149, in _exec_jsonrpc
    raise ConnectionError(
fatal: [device_1]: FAILED! => {
    "changed": false,
    "invocation": {
        "module_args": {
            "filename": "file.bin",
            "state": "present"
        }
    },
    "msg": "Connection error occurred: Failed to encode some variables as JSON for communication with ansible-connection. The original exception was: Object of type BufferedReader is not JSON serializable"
}

The way I provide a file to my request is by file-like object - open() in "rb" mode

I've also tried reading the file-like object and providing it this way

None of these approaches work

I was able to get it working using requests library with:

response = session.put(url, data=open("file.bin", "rb"), headers={"Content-Type": "application/octet-stream"})

Is is possible to upload a file using custom HttpApi plugin?

If so how do I provide the file to a request?

If any additional info is needed, let me know

Code snippet
