I have created a jira access token and also access the cloud id and providing all the necessity permission like jira:read and jira:work, but still not able to access the jira apis,

whenever i try to hit the api it shows the error message 

{
    "errorMessages": [
        "Issue does not exist or you do not have permission to see it."
    ],
    "errors": {}
}
