unable to run rest api to fetch issues from jira

[Vamsi Krishna Panthulu]

I am getting this error.  Not very good at scripting.  Taking assistance from GPT.

I want to fetch all issues from the project for a date range.  the ultimate goal is to fetch worklogs by author but even a simple list of issues is returning no results.  I confirmed by JQL in jira that there are issues for this query.

🔍 JQL Query: project = CSS AND created >= "2025-09-01" AND created <= "2025-09-10"
📦 Request Payload: {
"jql": "project = CSS AND created >= \"2025-09-01\" AND created <= \"2025-09-10\"",
"fields": [
"summary",
"status",
"created"
],
"pagination": {
"pageSize": 100
},
"reconcileIssues": true
}

📡 Response Status: 400
❌ Request failed: 400 Client Error: Bad Request for url: https://zlservicedesk.atlassian.net/rest/api/3/search/jql

✅ Downloaded 0 issues across 0 page(s).
