Robot Framework - Unsupported Media Type error - python-3.x

Question

I have the following json file:
{
"company":[
{
"name":"My company",
"security":"WPA2-PSK"
}
],
"name":"one name"
}
I'm trying to send a POST based on this json file but it's getting an error.
My code looks like this:
Create new company
${headers} = Create Dictionary Accept=application/json Content-Type=application/json
${body} = Get file create.json
Create Session http_session ${url} disable_warnings=${True}
${response} = POST On Session http_session ${company} data=${body} headers=${headers}
But I get the following error:
POST Response:
headers={'content-type': 'application/json', 'vary': 'Accept, Origin, Cookie', 'allow': 'GET, POST, HEAD, OPTIONS', 'x-frame-options': 'DENY', 'content-length': '52', 'x-content-type-options': 'nosniff', 'referrer-policy': 'same-origin', 'set-cookie': '64bc588b56c7114f53411b945693e29ba=55323dcbd60f99b6aa8cfcb0f44f578e; path=/; HttpOnly; Secure; SameSite=None'}
body={"detail":"Unsupported media type \"\" in request."}
HTTPError: 415 Client Error: Unsupported Media Type for url: myUrl
So I did:
Create new company
${headers} = Create Dictionary Accept=application/json Content-Type=application/json
${json1} = Get file create.json
${json} = Evaluate json.dumps(${json1})
${body} = Evaluate json.loads('''${json}''') json
Create Session http_session ${url} disable_warnings=${True}
${response} = POST On Session http_session ${company} data=${body} headers=${headers}
so i got the same error.
What did I do wrong?

Answer 1

It was a problem in converting json. I did it like this:
${body} = Evaluate json.loads("""${json}""")
Now it worked.
