userApi.blockUser(Int) is trying to read response as User.class instead #169
Description
blockUser method of UserApi class is looks like this right now:
public User blockUser(Integer userId) throws GitLabApiException {
if (userId == null) {
throw new RuntimeException("userId cannot be null");
}
Response response = post(Response.Status.CREATED, (Form) null, "users", userId, "block");
return (response.readEntity(User.class));
}
it's trying to read response as User.class entity response.readEntity(User.class), however I Gitlab API does not respond here with any kind of data similar to User.class, here's documentation:
https://docs.gitlab.com/ee/api/users.html#block-user
it only returns HTTP codes
201 OK on success, 404 User Not Found is user cannot be found or 403 Forbidden when trying to block an already blocked user by LDAP synchronization
As a result, when we're trying to block user like
gitLabApi.userApi.blockUser(gitlabUser.id)
we're getting exception:
Exception in thread "main" javax.ws.rs.ProcessingException: Error reading entity from input stream.
