Json – How can I use the term None instead of null in post request python project?

In python, I had this variable:

v = None

and this post request:

issue = {
                    "fields": 
                        {
                            "project": 
                            {
                                "id": 'x'
                            },
                            "summary": 's',
                            "issuetype": 
                            {
                                "name": 'n'
                            },
                            "components": 
                            [
                                {
                                "name": 'c1'
                                },
                                {
                                "name": v
                                },
                            ]
                         }

After debugging I got this error message:

‘{"errorMessages":[],"errors":{"components":"Component name ‘None’ is not valid"}}’

The data is dynamic and that v as well, in case it is entered as a string then that won’t be no issue at all but it if is empty in the entered data I want to skip in the post request then that will be an issue.

In postman I had no issue I add null to it and then it works.

It is just that in python where I cannot find a way to add that null. hence I tried None, ‘null’ and no way.

Isn’t there any solution for this?

                #convert dict to string
            r = json.dumps(issue)
             
            #Replace None by null in the string
            r = r.replace(""None"", "null")
            
            #convert back the string to dict
            loaded_r = json.loads(r)

            response_post = requests.post(
            url_post,
            headers=headers , 
            json =  loaded_r 
            )

    It looks like the post request is json format. The object you have is a python object; what you need is the json-formatted string equivalent:

    import json

type(issue) # dict
json_payload = json.dumps(issue, indent=2)
type(json_payload) # string

print(json_payload)
# {
#   "fields": {
#     "project": {
#       "id": "x"
#     },
#     "summary": "s",
#     "issuetype": {
#       "name": "n"
#     },
#     "components": [
#       {
#         "name": "c1"
#       },
#       {
#         "name": null
#       }
#     ]
#   }
# }
