Curl command for creating Github Repository is not working - json

Question

I tried the following code for creating a repository. But it gives JSON parsing problem. What causes this?. I took this code from https://docs.github.com/en/rest/reference/repos tried in python code using requests.post method. But that too gave the same error Problem Parsing JSON. Is this bad request or the parsing problem is inside Github API.
curl -i -H "Authorization: token MYACCESSTOKENHERE" \
-d '{ \
"name": "simp", \
"auto_init": true, \
"private": true, \
"gitignore_template": "nanoc" \
}' \
https://api.github.com/user/repos

Answer 1

Could you please validate your token is authorized.
Please refer Authorizing OAuth Apps
curl -H "Authorization: token OAUTH-TOKEN" <https://<your_repo_endpoint> -I
Update using JSON formatter
"-d""{ \\
\"name\": \"simp\", \\
\"auto_init\": true, \\
\"private\": true, \\
\"gitignore_template\": \"nanoc\" \\
}""\\

Answer 2

The problem is with the JSON format. After I removed unwanted lines and spaces from the curl command, it worked.
curl -i -H "Authorization: token 1f003ae8eab2feea72630d6f3150b921a522a868" -d '{ "name": "simp1", "private": true}' https://api.github.com/user/repos
