Python Unhashable when posting body in OKTA

Hello, anyone who can help me. I am having a TypeError: unhashable type: ‘dict’ when posting an application to a user with orgid.

body = {
{
“profile”: {
“orgId”: “johndoe@aaaaa.com"
}
}
}

responsePostApp = requests.post(f’{okta_url}/api/v1/apps/{appid}/users/{userid}', headers=headers, body=body, verify=False)

Im using python for the script and im having trouble with the unhashable error. Hope you can help me.
