Set the resolution field on create issue via REST API

Hi everyone,

I’m trying to set the resolution field when I create an issue through the REST API. But it seems that it is not set the the issue because I can see that it returned a null resolution. I don’t have any transition set on my workflow and no post functions. When I update the issue’s resolution through the REST API. The resolution is thus set.

Does anyone know how to achieve?

Thanks in advance,
Lâm
