TypeError: b'1' is not JSON serializable

Question

I am trying to send a POST request as JSON.

*email variable is of type \"bytes\"

def request_to_SEND(email, index):
    url = \".....\"
    data = {
         


        

Answer 1

This is happening because you're passing a bytes object in the data dict (b'1', specifically), probably as the value of index. You need to decode it to a str object before json.dumps can work with it:

data = {
    "body": email.decode('utf-8'),
    "query_id": index.decode('utf-8'),  # decode it here
    "debug": 1,
    "client_id": "1",
    "campaign_id": 1,
    "meta": {"content_type": "mime"}
}
