Hi @SemyonGashchenko, thanks for giving the feature a try.
Could you change context ID to this format:
"contextIds": ["ari:cloud:jira:{cloud ID}:workspace/{workspace ID}"]
if you don’t have the Workspace ID, please try passing Cloud ID instead, e.g.
"contextIds": ["ari:cloud:jira:{cloud ID}:workspace/{cloud ID}"]
