Issue description
When sending a request via the REST API, you get the Service account is not available error.
Solution
Assign the iam.serviceAccounts.user role to the service account or user sending the request.
Note
If you make a request on behalf of a service account, it must have the permission to use itself as a subject.
For example, Yandex Serverless Containers checks the permissions of the assigned service account when creating a new container revision.
