…ashes if provided a negative value
During the AWS outage today, the aws_credentials app ultimately was terminated because the supervisor reached the max restart intensity. The crash that was causing the restarts was:
,[{erlang,send_after,[-1000,<0.2314.0>,refresh_credentials],[{error_info,#{cause => time,module => erl_erts_errors}}]},{aws_credentials,setup_callback,1,Unfortunately, the actual value being returned for the expiration during this period was not in the stack trace. I'm sure this is an exceptional case but if the app were to remain running, it could, in theory recover once the service disruption is over.
