Error when create multiple streams by goroutine

When I create multiple streams by goroutine at the same time I catch error:
The HTTP request did not return a success code:
500 / {"@type":"statement_error","error_code":50000,"message":"The producer has been rejected from the broker because it tried to use an old epoch with the transactionalId","statementText":

Hi @ChiQuang98,
could you please give a code example so we can better understand the context?
