jira rest api, rendered field description failed to render images which are copy pasted

[Peter Janickovic]

When I receive Jira Issue via Rest API (using node jira-client) api v2, and using expand: [renderedFields] images which were copy pasted to description are not rendered correctly and error of this type is rendered: unable to embed resource xy of type application/octet

when images are uploaded, it works just file.

is there anything I am doing wrong ?
