REST API create project - leadAccountId is throwing an error

[Rajinish_Gaddam]

I'm using python REST document to create a project but I was getting an Internal server error. I didn't find any solution, please help thanks in advance.

payload = json.dumps({
  "notificationScheme": 10021,
  "description": "Example Project description",
  "leadAccountId": "<accountId>",
  "url": "http://atlassian.com",
  "projectTemplateKey": "com.atlassian.jira-core-project-templates:jira-core-simplified-process-control",
  "avatarId": 10200,
  "issueSecurityScheme": 10001,
  "name": "Example",
  "permissionScheme": 10011,
  "assigneeType": "PROJECT_LEAD",
  "projectTypeKey": "business",
  "key": "EX",
  "categoryId": 10120
}
)
