Project search & issue type API's are not working with authorization code, giving blank array

[Khushal Singh]

When i am trying to call some api's with token generated from code using correct client_secret & client_id, api's giving blank array in response,

like,

https://<my domain>/rest/api/3/project/search

"Authorization: Basic <base64 >"  (  base64 code is made with base64(username:token)  )

it gives blank array [], also other API's like issue type & issue list

but,

When i pass token from jira dashboard from this place "https://id.atlassian.com/manage-profile/security/api-tokens", API's works fine,

Please provide help, if there is any permission related issue then also help to locate me to on those permissions,

Thanks in Advance....
