Hi @azakovorotny ,
Your issue will be different than the others referred to in this thread as the initial poster was using the Spring Cloud Stream binder which does NOT use JMS.
Given your error it looks like your client-username doesn’t have permission to create the endpoint. Can you check your “my_cp” client-profile and see if it has “Allow Client to Create Endpoints” set to true?
If it’s already set to true please go ahead and create a separate discussion in the forum to avoid confusion for others that find this thread in the future.
Hope that helps!
