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
