Bolt 5 API. Need an example of how to create a resource using api.

[igoreshik001]

I am unable to create the resource. That's what I'm doing:
curl -X 'POST'
'http://127.0.0.1:8000/api/contents'
-H 'accept: application/json'
-H 'Content-Type: application/json'
-d '{
"contentType": "my-mail",
"status": "published",
"createdAt": "2022-04-29T04:30:47.749Z",
"modifiedAt": "2022-04-29T04:30:47.749Z",
"publishedAt": "2022-04-29T04:30:47.749Z",
"depublishedAt": "2022-04-29T04:30:47.749Z",
"fields": [
{
"name": "name",
"content": "text",
"value": [
"name2"
]
}
]
}'

This is my config/contenttypes.yaml
my-mail:
name: My Mail
singular_name: My Mail
fields:
name:
type: text
firma:
type: text
email:
type: email
message:
type: textarea
city:
type: text
checkbox:
type: checkbox
taxonomy: [ categories, tags, foobars ]
records_per_page: 5
order: id
icon_many: "fa:envelope"
icon_one: "fa:envelope"

Here is what comes in response:
